To reject Jesus Christ is to reject the only begotten Son of God is to reject God is to reject Eternal Life: “Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God” (Psalm 90:2).
“For there is one God, and one mediator between God and men, the man Christ Jesus: who gave himself a ransom for all, to be testified in due time” (1 Timothy 2:5–6).
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved. He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God” (John 3:16-18).
