Read 1 John 1:5–7
If we walk in the light, as [God] is in the light, we have fellowship with
one another, and the blood of Jesus, his Son, purifies us from all sin.
1 John 1:7

Every form of life has its enemies. Insects have to watch out for hungry
birds, and birds must keep an eye on hungry cats and dogs. Even human
beings have to dodge automobiles and fight off germs. The life that is real also has an enemy, and we read about it in this section of 1 John. This enemy is sin.

John illustrates his theme by using the contrast between light and
darkness: God is light; sin is darkness. The New Testament calls the
Christian life a “walk.” This walk begins with a step of faith when people
trust Christ as their Savior. But salvation is not the end—it is only the
beginning—of spiritual life. “Walking” involves progress, and Christians
are supposed to advance in the spiritual life. Just as a child must learn to
walk and must overcome many difficulties in doing so, a Christian must
learn to “walk in the light.” And the fundamental difficulty involved here is
this matter of sin.

Something to Ponder
When you identify a recurring sin in your life, how do you deal with it? Can you think of any potential sin in your life right now that needs attention?
