Man does not change in order to be saved, but true salvation always brings about an evident change in the life of the new believer. Perhaps the change is less noticeable in some new believers and more noticeable in others; however, no change means no salvation. The change is not always an immediate outward change because it involves a change of the inward nature. A person who trusts Christ for salvation becomes a new creature (Galatians 6:15). It might be best to consider how this could be likened to a dog (Matthew 15:26-27) becoming a sheep (John 10:16). A new man now dwells within the new Christian to help combat and defeat the old sinful nature (Ephesians 4:22-24). Salvation is not merely the turning over of a new leaf; it is a new birth (John 3:3) where one is passed from spiritual death to spiritual life (John 5:24).
God created man without sin. In his infancy, man had no knowledge of evil but knew only the joys of fellowship with God. The first man had a perfect environment, a perfect spouse, and an uncorrupted mind. He had little in the way of commandments as God only gave one “thou shalt not” (Genesis 2:16-17). Of all the things man could have done within the will of God, man chose to violate God’s one restriction by partaking of the tree of the knowledge of good and evil. Immediately man’s eyes were opened to good and evil, and he died spiritually just as God had promised. In order to rescue man, God sacrificed an animal, providing coats of skin to cover man’s nakedness, and removed him from the garden.
