​In this the children of God and the children of the devil are manifest: Whoever does not practice righteousness is not of God, nor is he who does not love his brother (1 John 3:10).
 
If “righteousness” is the demarcation between children of the devil and children of God, we’d better understand what it is so we can practice it. We know that God is love. We know that God is light, or truth. We know that His kingdom if comprised of righteousness, peace and joy.
 
So what can we conclude? If we are to practice righteousness, then we are to practice love. We are to practice being light, which is practicing truth. We are to practice Peace and Joy.

Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God (1 John 3:9).
 
I confess. I still sin. Probably I speak for you as well when I admit that sometimes I worry, I can still be fearful, I complain now and then, I’m not always filled with love and faith isn’t always my platform. Let me quickly say I don’t deliberately choose these things, they seem to pop up of their own volition.
 
However, because I am born of God I instantly know I have sinned and I know who inspired these things to pop up—the devil! We cannot keep him from feeding us lines to say and ideas to think, but the best way to defeat him is to starve him to death. In other words, don’t do what he inspires us to do or to say and if we fall, repent and quickly ask the Lord to forgive. We choose, and the Holy Spirit helps, to turn our words and our thinking around because God’s Seed does remain in us.
