Welcome back to "The Way of the Word." We are moving deep into the heart of the New Testament, into a letter that feels like a warm embrace and a sharp wake-up call all at once. If you’ve ever wondered what it looks like to truly "know" God: not just know about Him, but to walk in a living, breathing, vibrant relationship with the Creator of the universe: then 1 John is your handbook.
In this chapter of our study guide, we are looking at the Apostle John’s first epistle. John isn’t interested in abstract theology that stays in your head. He’s interested in truth that gets under your skin, changes your heart, and transforms how you treat the person sitting next to you in the pew. He writes with the urgency of a father and the authority of an eyewitness.
Let’s dive into the light and the love of God.
The Context: A Letter of Certainty
Before we jump into the verses, we have to understand why John picked up the pen. He was the "beloved disciple," the one who leaned against Jesus at the Last Supper. By the time he wrote this, he was likely the last surviving apostle. He was writing to believers in Asia Minor (modern-day Turkey) who were being rattled by false teachers.
These teachers (early Gnostics) were claiming that "spirit" was good but "matter" was evil. This led to two dangerous errors: some said it didn't matter what you did with your body (leading to immorality), and others denied that Jesus actually came in the flesh (Docetism).
John steps in with a roar of pastoral love. He says, "I saw Him. I heard Him. I touched Him." He brings us back to the reality of the Incarnation and the practical necessity of holiness. For John, Christianity is about three things: the right belief (Jesus is the Son of God), the right behavior (obedience to His Word), and the right heart (love for others).
Part 1: Walking in the Light (1 John 1)
Scripture Focus: 1 John 1:5–7
"This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin."
John begins with a foundational truth: God is Light.
In biblical imagery, light represents two things: truth (intellectual) and holiness (moral). Darkness represents falsehood and sin. John is making a logical argument here that cuts through the "spiritual" fluff of his day. You cannot claim to be in fellowship with a God who is pure Light while you are choosing to live in the shadows of intentional, unrepentant sin.
From an Assemblies of God perspective, we emphasize that salvation is a transformative experience. It isn’t just a legal transaction; it’s a change of kingdom. We move from the kingdom of darkness into the kingdom of His marvelous light.
The Reality of "Walking" Notice the word "walk." It implies a direction, a lifestyle, and a steady progress. It doesn't mean "perfection." John is very clear in verses 8 and 10 that if we claim we have no sin, we’re lying. Walking in the light doesn’t mean you never trip; it means when you do trip, you fall toward the Light. You don't hide your sin in the dark; you bring it into the light of God’s presence, you confess it, and you let the blood of Jesus cleanse you.
The Double Result When we walk in the light, two things happen:
Fellowship with one another: True community is impossible in the dark. In the dark, we wear masks. We hide our struggles. We pretend. But in the light, we are honest. Honest people can have real fellowship.
Ongoing Cleansing: The Greek tense for "purifies" or "cleanses" in verse 7 is continuous. It’s a constant stream. As we walk with Him, the blood of Jesus is continuously working to keep us clean.
Practical Application: Is there a part of your life you are trying to keep in the "dark"? Maybe a habit, a resentment, or a secret? Bring it to the Light today. Confess it to God. Find a trusted brother or sister in Christ to talk to. The Light doesn't exist to shame you; it exists to heal you.
Part 2: The Advocate and the Test of Knowing (1 John 2)
Scripture Focus: 1 John 2:1–2
"My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father: Jesus Christ, the Righteous One. He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world."
John uses a tender term here: "My dear children." He’s not lecturing from a pedestal; he’s mentoring from a heart of love. He sets a high bar: "I write this so that you will not sin": but he immediately provides the safety net of grace.
Our Advocate in the Courtroom The word "Advocate" (Parakletos) is the same word used for the Holy Spirit in John’s Gospel. It means someone called alongside to help, like a defense attorney. When we sin, Satan is "the accuser of the brethren" (Revelation 12:10). He stands before God pointing at our failures. But Jesus, our Advocate, doesn't argue our innocence (because we aren't innocent). Instead, He points to His own wounds. He says, "I paid for that one. That debt is settled."
Jesus is our "atoning sacrifice" (or propitiation). This means He turned away the wrath of God by taking it upon Himself. This is the core of our faith. We don't walk in the light to earn God’s favor; we walk in the light because Jesus bought us back and made us His own.
The Test of Obedience How do we know if we really "know" Him? John gives us a simple test: Do we keep His commands? (1 John 2:3). If someone says, "I’m a great friend of the King," but they constantly ignore the King’s laws and mock the King’s character, you’d doubt their friendship. True knowledge of God leads to a desire to please Him.
The New (and Old) Commandment John then points to the "new" commandment: Love your brother. It’s old because it’s been there since the beginning, but it’s new because Jesus gave it a new standard: "As I have loved you, so you must love one another" (John 13:34).
If you claim to be in the light but hate your brother, John says you are still in the darkness. This is a heavy word for the church today. We cannot separate our vertical relationship with God from our horizontal relationship with people.
Part 3: Love Not the World (1 John 2:15–17)
John gives a stern warning about "the world." He isn't talking about the physical planet or the people on it (God loves the world!). He’s talking about the system: the values and priorities that operate independently of God.
He breaks it down into three categories:
The lust of the flesh: The craving for physical pleasure at the expense of God’s will.
The lust of the eyes: The greed for everything we see; the "I want that" spirit.
The pride of life: The obsession with status, power, and being "somebody" in the eyes of men.
John reminds us that the world and its desires pass away. Only the one who does the will of God lives forever. In our modern culture, where social media feeds the pride of life and advertising feeds the lust of the eyes, this warning is more relevant than ever.
Part 4: The Great Love of the Father (1 John 3)
Scripture Focus: 1 John 3:1
"See what great love the Father has lavished on us, that we should be called children of God! And that is what we are!"
Stop and let that sink in. The word for "great" or "what kind" in the Greek (potapen) literally means "from what country" or "how foreign." John is saying that God’s love is so unlike anything on this earth that it’s almost alien. It’s otherworldly.
We aren't just "servants" or "subjects." Through Christ, we are adopted into the family. We are children. This is our identity.
Living as Children Because we are children of a holy Father, we pursue holiness. John explains that "no one who is born of God will continue to sin" (1 John 3:9). Again, this doesn't mean sinless perfection, but it means a change in disposition. A pig loves the mud; a sheep might fall in the mud, but it wants to get out. When we are born of God, we receive a new nature that is incompatible with a lifestyle of habitual, comfortable sin.
The Proof of Love John moves from the "what" to the "how." How do we know what love is? "Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters" (1 John 3:16). Love isn't a feeling in 1 John; it's a verb. It’s "not with words or speech but with actions and in truth" (3:18). If you see a brother in need and have the means to help but close your heart, the love of God is not in you.
Part 5: God is Love (1 John 4)
This brings us to the climax of the letter.
Scripture Focus: 1 John 4:7–12
"Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love... This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins."
John doesn't just say God acts lovingly; he says God is love. Love is His very essence.
The Manifestation God didn't just shout "I love you" from heaven. He showed it. He sent His Son. This is the ultimate proof of love: the Cross. At the Cross, the "Light" of God’s holiness met the "Love" of God’s heart.
The Responsibility Because God loved us this way, we have a responsibility to love others. "No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us" (1 John 4:12). Think about that: people can't see God, but they see us. When we love each other with the sacrificial love of Christ, we make the invisible God visible to the world.
Perfect Love Casts Out Fear John addresses the fear of judgment. If we are walking in His love, we don't have to be terrified of the day of judgment. Why? Because "as He is, so are we in this world" (4:17). We are covered by His righteousness. Punishment and fear don't belong in the heart of a child who knows they are deeply loved by their Father.
Part 6: Victory in Faith (1 John 5)
John concludes his letter by focusing on the power of faith. "Everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith" (1 John 5:4).
Our faith is not in a philosophy or a feeling; it’s in a Person: Jesus Christ, the Son of God. John emphasizes the "testimony" of the water (Jesus' baptism), the blood (His death), and the Spirit. All three testify to who Jesus is.
The Certainty of Eternal Life The purpose of the whole letter is summed up in 5:13: "I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life." John wants you to have assurance. You don't have to guess. You don't have to wonder. If you believe in the Son, if you are walking in the light, and if you are practicing love, you can know that you belong to Him.
The Closing Warning The very last verse of the letter seems almost abrupt: "Dear children, keep yourselves from idols" (5:21). After all this talk about light and love, why end with idols? Because an idol is anything that takes the place of the "true God and eternal life" (5:20). Anything that distracts us from walking in the light or living in His love is an idol. John’s final plea is for us to stay focused on the real Jesus.
Theological Reflection: The Holy Spirit in 1 John
While the word "Pentecostal" isn't in the text, the reality of the Spirit’s work is everywhere in 1 John. John speaks of the "anointing" (charisma) that we have from the Holy One (2:20, 27). This anointing teaches us and helps us discern truth from error.
In the Assemblies of God, we believe the Holy Spirit is our primary source of power for living the life John describes. We cannot love like Jesus on our own strength. We cannot walk in the light by sheer willpower. We need the indwelling and empowering presence of the Holy Spirit to produce the "fruit of the Spirit" (Galatians 5:22-23), the first of which is love.
When we are baptized in the Holy Spirit, it shouldn't just result in spiritual gifts; it should result in a deeper love for God and a greater compassion for people. If our "spirituality" doesn't lead to the kind of practical love John describes, we need to check which spirit we are following.
Practical Study: Living the Word
As you study 1 John this week, ask yourself these diagnostic questions:
The Truth Test: Do I believe that Jesus is the Son of God, come in the flesh, to be the only Savior of the world? Do I rely on His blood alone for my cleansing?
The Obedience Test: Is there a command of God that I am currently ignoring? Am I seeking to align my life with His Word, or am I trying to "walk in darkness" while claiming to be a Christian?
The Love Test: Is there someone in my life (a "brother") whom I am harboring hatred or resentment toward? How can I practically show the love of Christ to someone in need this week?
Prayer of Response: Father, thank You for Your otherworldly love. Thank You for calling me Your child. I confess that I sometimes wander into the shadows. Help me to walk in the Light as You are in the Light. Cleanse me from all unrighteousness. Fill me with Your Holy Spirit so that I can love others the way You have loved me. Keep me from idols and keep me close to Jesus. Amen.
