And because we are all sinful, we are all cut off from God. In fact it is even worse than that. From our birth we are in Adam's family and inherit the effects of Adam's sin. We are dying creatures from our beginning. And then we all make things worse by adding our own sins.
Men can do nothing to save themselves.
Saved by God's grace God, in His love and His pity, did not leave men to die in their sins . He found a way in which they could come to Him and have life. God's grace is His love which He gives us freely, forgiving us for Christ's sake. He has done His part. He has given us Jesus.
