'Obey' in the Bible

And by this we may know that we know Him--if we obey His commands.

Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him.

and we receive from Him whatever we ask because we [carefully and consistently] keep His commandments and do the things that are pleasing in His sight [habitually seeking to follow His plan for us].

The one who habitually keeps His commandments [obeying His word and following His precepts, abides and] remains in Him, and He in him. By this we know and have the proof that He [really] abides in us, by the Spirit whom He has given us [as a gift].

This is how we know that we love God’s children when we love God and obey His commands.
