'Keep' in the Bible

And this is how we know [daily, by experience] that we have come to know Him [to understand Him and be more deeply acquainted with Him]: if we habitually keep [focused on His precepts and obey] His commandments (teachings).

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.

As for you, let that remain in you [keeping in your hearts that message of salvation] which you heard from the beginning. If what you heard from the beginning remains in you, you too will remain in the Son and in the Father [forever].

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].

By this we know [without any doubt] that we love the children of God: [expressing that love] when we love God and obey His commandments.

For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].

Little children (believers, dear ones), guard yourselves from idols—[false teachings, moral compromises, and anything that would take God’s place in your heart].
