21I have not written to you because you do not know the truth, but because you do know it, and because no lie is of the truth. 22Who is the liar except the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son. 23Whoever denies the Son does not have the Father; the one who confesses the Son has the Father also. 24As for you, see that what you heard from the beginning remains in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.
25This is the promise which He Himself made to us: eternal life.
26These things I have written to you concerning those who are trying to deceive you.
