1 John 1:6

1 John 2:4 NIV
Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.

1 John 4:20 NIV
Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen.

John 3:19-21 NIV
This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil. Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.
