1 John 3:10

By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.

3 John 1:11

Beloved, do not imitate what is evil, but [imitate] what is good.

1 John 4:6

We [who teach God’s word] are from God [energized by the Holy Spirit], and whoever knows God [through personal experience] listens to us [and has a deeper understanding of Him].
