But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. 1 John 1:7 (ESV)
If we walk in the light of God’s ways and truth as he does, we will experience fellowship with other believers. Our lives will be cleansed of the stains that sin has brought and we will progressively walk more and more in God’s ways.
