I love the honesty and the intentionality of this passage...like a father calling out his kids "stop, there is a car coming."  We need to truly be aware if we are practicing a sinful life, and if we are, we're running against the freedom that Jesus died for.

1 John 3:8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil.
