1John 2:3-6 (NIV) We know
that we have come to know him if we
obey his commands.
4 The man who says,
"I know him," but does not do what he commands is
a liar, and the truth is not in him.
5 But if anyone obeys his
word, God's love is truly made complete in
him. This is how we know we are in him:
6 Whoever claims to live
in him must walk as Jesus did.
