Who is the liar but the one who denies that Jesus is the Christ ? This is the antichrist, the one who denies the Father and the Son.
Whoever denies the Son does not have the Father ; the one who confesses the Son has the Father also.
As for you, let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father.
By this the love of God was manifested in us, that God has sent His only begotten Son into the world so that we might live through Him.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.
If we receive the testimony of men, the testimony of God is greater ; for the testimony of God is this, that He has testified concerning His Son.
The one who believes in the Son of God has the testimony in himself ; the one who does not believe God has made Him a liar, because he has not believed in the testimony that God has given concerning His Son.
And the testimony is this, that God has given us eternal life, and this life is in His Son.
He who has the Son has the life ; he who does not have the Son of God does not have the life.
And we know that the Son of God has come, and has given us understanding so that we may know Him who is true ; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
