In Genesis 3:16-19 we see how God punished Adam and Eve because of their disobedience. Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire [shall be] to thy husband, and he shall rule over thee. And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed [is] the ground for thy sake; in sorrow shalt thou eat [of] it all the days of thy life; Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field; In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou [art], and unto dust shalt thou return.
Sin brings with it many undesirable effects. They would be cast out of the garden, their remaining time on earth would be spent in labor, and ultimately they would die a physical death. Do you think if Adam and Eve had known where their sin would lead them, do you think they would have fallen for Satan’s lies? If we thought about the guilt and destruction sin brings to our lives, would we want to sin?
A principle is established with the first two people on earth – sin brings punishment. This is why the blood of Christ is so important. The blood covers the sins of a Christian when he or she repents. There is still a price to pay for sin, and ultimately we will all die a physical death, but spiritually the penitent Christian has the hope of eternal life through the blood of Christ.
