1 John

Fellowship with God

The Goal: Assurance.
"I write these things... that you may know that you have eternal life."

BEGIN STUDY
Introduction

The Context

Written by the Apostle John (author of the Gospel of John) around 85-95 AD. He was an old man, addressing believers as "little children."

The Threat: Gnosticism

False teachers claimed the physical body was evil and only the "spirit" mattered. This led to two errors:

  • Licentiousness: "Sinning in the body doesn't hurt my spirit."
  • Asceticism: Denying Jesus came in the flesh.
Reflection

John emphasizes physical reality ("...which our hands have touched"). Why is it important to your faith that Jesus was physically real, not just a spirit?

1 John 1:5-10

Light & Darkness

"God is light, and in him is no darkness at all." (1:5)

You cannot have fellowship with God while walking in darkness. John destroys the idea that we can hide secret sins while claiming to be close to God.

The Solution: Confession
Reflection

Is there an area of your life you are keeping in the "dark"? What stops you from bringing it into the light today?

1 John 2:1-6

The Advocate

John writes so we do not sin. But if we do, we aren't hopeless. We have a defense attorney.

Jesus as "Propitiation"

A big theological word. It means Jesus didn't just cover the sin; He satisfied the wrath of God associated with it. The debt is fully paid, not just ignored.

"Whoever says 'I know him' but does not keep his commandments is a liar." (2:4)
Reflection

How does knowing Jesus is your "Advocate" (Lawyer) change how you feel when you make a mistake? Does it lead to freedom or fear?

1 John 2:7-17

Love & The World

New Commandment Do Not Love World

The "New Commandment" is actually old: Love one another. But John pivots to a warning: You cannot love the Father and the World simultaneously.

The 3 Enemies (v16)

Lust of the Eyes

Greed, materialism, coveting.

Lust of the Flesh

Sensual pleasure, gluttony, laziness.

Pride of Life

Arrogance, status, self-sufficiency.

Reflection

Which of the "Three Enemies" competes most for your heart right now?

1 John 3:1-10

Children of God

"See what kind of love the Father has given to us, that we should be called children of God!" (3:1)

This is the core identity slide. We are not just servants; we are family. This identity demands a lifestyle change.

The DNA Test

John uses stark language: "No one born of God makes a practice of sinning."

He isn't claiming perfection (remember 1:9). He is describing trajectory. A child of God cannot be comfortable in habitual, unrepentant sin.

Reflection

Does your life show a "family resemblance" to the Father? What recent victory over sin gives you assurance of this?

1 John 3:11-24

Love in Action

Love is not a feeling; it is a sacrifice. John contrasts Cain (murder/hate) with Christ (sacrifice/love).

😡
Cain

Hated his brother because his own deeds were evil.

✝️
Christ

Laid down his life for us. We ought to do the same.

"Let us not love in word or talk but in deed and in truth." (3:18)
Practical Check: If you see a brother in need and close your heart against him, how does God's love abide in you? (v17)
Reflection

Identify one person you can love "in deed" this week. What specific action will you take?

1 John 4:1-6

Test the Spirits

Not every spiritual experience is from God. We must be discerning.

🧪 The Litmus Test
REVEAL
"Little children, you are from God and have overcome them, for he who is in you is greater than he who is in the world." (4:4)
Reflection

In an age of "spiritual but not religious," how do you personally vet the content (podcasts, books, influencers) you consume?

1 John 4:7-21

God is Love

The most famous definition of God in the Bible. But John clarifies: We love, only because He first loved us.

Perfect Love

"There is no fear in love, but perfect love casts out fear." (4:18)

Fear has to do with punishment. If you are afraid of God's judgment, you haven't fully grasped His love for you in Christ.

Reflection

Are you motivated to obey God by fear of punishment or by love? How would your daily life change if fear was completely removed?

1 John 5:1-12

Overcoming

"And this is the victory that has overcome the world—our faith." (5:4)

Faith isn't just a mental assent; it is the engine of victory. It makes God's commandments not "burdensome."

The Testimony

God gave us eternal life, and this life is in his Son.

The Binary

"Whoever has the Son has life; whoever does not have the Son of God does not have life." (5:12)

Reflection

Do you view God's commandments as a heavy burden or a pathway to life? What makes them feel burdensome?

1 John 5:13-21

Confidence

The book concludes with assurance. We can KNOW we are saved. We can KNOW he hears our prayers.

The Final Verse (5:21) "Little children, keep yourselves from idols."

After 5 chapters of theology, he ends with this abrupt command. Why? Because anything that replaces the true God (as defined in this letter) is an idol.

Reflection

What is the biggest "idol" (something you trust for happiness or security more than God) threatening your spiritual life today?
