I have not written unto you because you know not the truth, but because you know it, and that no lie is of the truth. Who is a liar but he that denies that Jesus is the Christ? He is antichrist, that denies the Father and the Son. Whosoever denies the Son, the same has not the Father: but he that confesses the Son has the Father also. Let that therefore abide in you, which you have heard from the beginning. If that which you have heard from the beginning shall remain in you, you also shall continue in the Son, and in the Father. And this is the promise that he has promised us, even eternal life. (1 John 2:21-25)
