There are many gifts that are given us by God, but eternal life and power are not among them. You are probably asking how I can say such a thing. Aren't these part of the promise we have been given? In a way, I am dealing with semantics. God doesn't give us eternal life, but we do experience it when the life that is Jesus comes into us. I like the way Oswald Chambers put it when he said "Eternal life is not a gift from God, eternal life is the gift OF GOD." You see, when we accept Jesus, and He enters into us, we have no choice but to live forever because that is His nature.
