Life at its best, having infinite duration characterized by abiding fellowship with God. This important term in the NT is emphasized in the Gospel of John but also appears in the other Gospels and in Paul’s writings. Eternal life in the NT eliminates the boundary line of death. Death is still a foe, but the one who has eternal life already experiences the kind of existence that will never end.
Yet, in this expression, the emphasis is on the quality of life rather than on the unending duration of life. Probably some aspects of both quality and duration appear in every context, but some refer primarily to quality of life, and others point to unending life or a life to be entered into in the future.
In terms of quality, life is (1) life imparted by God; (2) transformation and renewal of life; (3) life fully opened to God and centered in Him; (4) a constant overcoming of sin and moral evil; and (5) the complete removal of moral evil from the person and from the environment of that person.
