Eternal life is the nature of God that is imparted to man at the new birth, making him a new creation. Man's need of Eternal Life was the reason for Redemption. "I came that they may have life and may have it abundantly." (John 10:10). "Even as thou gavest Him authority over all whom thou has give Him that He should give Eternal Life, and this is Life eternal that they should know thee the only true God, and Him whom thou didst send even Jesus Christ." (John 17:2-).
"Verily, verily, I say unto you, He that heareth my word, and believeth him that sent me hath Eternal Life, and cometh not unto judgement, but hath passed out of death into life." For as the Father hat life in Himself even so gave He to the son also to have life in Himself." (John 5:24, 26).
"Whereby He hath granted unto us His precious and exceeding great promises; that through these ye may become partakers of the Divine nature." (2 Peter 1:1).
