“But if we walk in the light as He is in the light, we have fellowship with
one another, and the blood of Jesus Christ His Son cleanses us from all sin”
(1 John 1:7).
Completing his contrast between those walking in darkness and those walking in
the light, John presents the positive side of this picture. By continuing to “walk(ing)
in the light,” not only do we have fellowship with God but also we have fellowship
with one another.
Those who are walking in the light with God are those who have accepted a common
set of spiritual values by obeying the gospel, culminating in baptism, and have made
it their goal to live the kind of lifestyle prescribed in the New Testament.
John adds a component in this passage when he designates the atoning factor that
makes this kind of fellowship possible: the blood of Jesus Christ, God’s Son. Without
that blood, there would be no possibility of fellowship with God.
