1 John 5:9-10, 18-21

If we take human testimony at face value, how much more should we be reassured when God gives testimony as he does here, testifying concerning his Son. Whoever believes in the Son of God inwardly confirms God’s testimony. Whoever refuses to believe in effect calls God a liar, refusing to believe God’s own testimony regarding his Son.

We know that none of the God-born makes a practice of sin—fatal sin. The God-born are also the God-protected. The Evil One can’t lay a hand on them. We know that we are held firm by God; it’s only the people of the world who continue in the grip of the Evil One. And we know that the Son of God came so we could recognize and understand the truth of God—what a gift!—and we are living in the Truth itself, in God’s Son, Jesus Christ. This Jesus is both True God and Real Life. Dear children, be on guard against all clever facsimiles.
