Charles Spurgeon Commentary 1 John 2:22-23

"Who is the liar but he that denieth that Jesus is the Christ? This is the antichrist, [even] he that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father: he that confesseth the Son hath the Father also." — 1 John 2:22-23 (ASV)

Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. Whosoever denieth the Son, the same hath not the Father: [but] he that acknowledgeth the Son hath the Father also.

Some pretend to honour the Father while they dishonour the Son, but this can never really be done. Jesus truly said, I and my Father are one, so that he who denies the Son denies the Father also.

Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. Whoever denieth the Son, the same hath not the Father:

They who deny the Deity of Christ practically deny the Divine Fatherhood of God. It is not possible for us to understand the rest of truth if we do not believe in Christ, who is the Truth. As the poet says: "You cannot be right in the rest
Unless you think rightly of him."
