Let us look first then at the origin of death. Death is not natural, in the sense that it was not there from the beginning. When God first created the world, it was full of life, and there was no death anywhere. Adam was created in the image of God for fellowship with God. God entered into a covenant with him, promising him life on condition of perfect obedience, but threatening death on disobedience. If he obeyed God, he would live forever. But there was in the middle of the Garden of Eden the tree of knowledge of good and evil.
