'Continue' in the Bible

Let that therefore abide in you, which ye have heard from the beginning. If that which ye have heard from the beginning shall remain in you, ye also shall continue in the Son, and in the Father.

And now, dear children, continue in union with Him; so that, if He re-appears, we may have perfect confidence, and may not shrink away in shame from His presence at His Coming.

But if any one has this world's wealth and sees that his brother man is in need, and yet hardens his heart against him--how can such a one continue to love God?

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].

These things I have written to you who believe in the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God.
