ScriptureDepth's study of 1 John 1
“If we say that we have fellowship with him and walk in the darkness, we lie, and don’t tell the truth.”
1 John 1:6
The author speaks to believers about the reality of their relationship with God, asserting that claiming fellowship while living in darkness is a lie that undermines truth.
What 1 John 1 is about
The speaker refers to what was from the beginning, declaring the Word of life, which was seen and touched (vv. 1-2). This testimony is shared to establish fellowship with the Father and His Son, Jesus Christ, and to fulfill joy (vv. 3-4). The message conveyed is that God is light, and there is no darkness in Him at all (v. 5). The text states that if one claims to have fellowship with God while walking in darkness, they are lying (v. 6). However, if one walks in the light, they have fellowship with one another, and the blood of Jesus cleanses from all sin (v. 7). The speaker asserts that denying sin is self-deception, as the truth is not in those who do so (vv. 8-9). If sins are confessed, God is faithful to forgive and cleanse from unrighteousness (v. 9). Claiming not to have sinned makes God a liar (v. 10).
If we confess our sins, God is faithful and just to forgive us and cleanse us from all unrighteousness.

Main themes in 1 John 1
Incarnation
In verses 1-2, the author speaks about 'that which was from the beginning,' referring to the Word of life who was 'with the Father' and was 'revealed to us.' This revelation is foundational, as the writer asserts having 'heard,' 'seen,' and 'touched' the Word, affirming the tangible reality of Jesus' incarnation. The chapter establishes a direct connection between the physical experience of the apostles and the divine nature of Christ.
Fellowship
Verses 3-4 focus on the theme of fellowship, declaring that the witness of the apostles aims to share their experience so that others may have 'fellowship with us' and with 'the Father' and 'his Son, Jesus Christ.' This mutual sharing of experiences is crucial for the joy of both the apostles and the recipients. The chapter thus connects the joy of believers to a shared community rooted in Christ.
Light vs. Darkness
In verses 5-7, the text states that 'God is light, and in him is no darkness at all.' The contrast between light and darkness illustrates the moral and spiritual truths about God's nature. The call to 'walk in the light' signifies a lifestyle aligned with God's purity, fostering genuine fellowship among believers. Walking in light is essential for experiencing true community and cleansing from sin.
Confession and Forgiveness
Verses 8-10 address the nature of sin and confession. The author asserts that claiming 'no sin' is self-deception and contradicts the truth. The promise in verse 9 reveals that if believers confess their sins, God is 'faithful and righteous' to forgive. This establishes a pathway to restoration and highlights the relationship between acknowledgment of sin and receiving divine forgiveness.
