1 John 1:5-10

Here John relates to his readers a most important message, “God is light” (vs. 5).

This truth has far reaching implications. For example, if we are tempted and sin, it is not God’s fault. He is not responsible for temptation, and we are solely responsible for our own sinful actions (cf. James 1:13-15).

Second, (and the point of these verses), we can not practice sin and be in fellowship with God. As there is “no darkness” in him, those who “walk in darkness” can have no part with God.

That’s not to say that we never sin. In fact, John here says we are lying to ourselves, and also accusing Christ of lying if we say we are not guilty of sin. The fact that Jesus came to earth to die for our sins indicates that we all are guilty. John here affirms the same.
What this does indicate is that God requires us to seek to live righteously. When we sin, we are required to confess those sins to God, and ask forgiveness. God is gracious and faithful in forgiving us upon our repentance.

Have you sinned? Ask God’s forgiveness! We must walk in the light to have to have fellowship with Him.
