19They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us. 20But ye have an unction from the Holy One, and ye know all things. 21I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth. 22Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.23Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also. 24Let 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. 25And this is the promise that he hath promised us, even eternal life.
