Now I am a child of God, and what I shall be has not yet been revealed. I know that when He is revealed, I shall be like Him, for I shall see Him as He is. And everyone who has this hope in Him purifies himself, just as He is pure. (1 John 3:2-3)
This is God's commandment: that we believe in the name of His Son, Jesus Christ, and love one another as He commanded us. (1 John 3:23)
Those who obey Christ's commandments abide in Him, and He in them. And this is how I know that He abides in me: by the Spirit whom He has given me. (1 John 3:24)
