We know that the Son of God has come, and has given us insight to know Him who is the Real God; and we are in Him who is real, even in his Son Jesus Christ. This is the real God, this is life eternal.
He who believes in the Son of God possesses that testimony within himself; he who will not believe God, has made God a liar by refusing to believe the testimony which God has borne to his Son.
I obtained mercy, for the purpose of furnishing Christ Jesus with the chief illustration of his utter patience; I was to be the typical instance of all who were to believe in him and gain eternal life.
It is the will of my Father that everyone who sees the Son and believes in him should possess eternal life, and that I should raise him up on the last day."
so that, while sin had reigned the reign of death, grace might also reign with a righteousness that ends in life eternal through Jesus Christ our Lord.
