And so the first man was driven out of God's garden, and there has never been any way back to it at all! No way back to God either, for Adam or for his children, except through Christ, "the Second Man, the Lord from Heaven." It was of this wonderful way, of Him who is "the Way," that God spoke when He told the serpent that the Seed of the woman should bruise his head. The Lord Jesus Christ was "the Seed," the One who loved us and gave Himself for us: the One whom "God so loved the world" as to give, "that whosoever believes in Him should not perish, but have everlasting life;" the One who "once suffered for sins, the just for the unjust, that He might bring us to God." We have been learning something of how dreadful the bites of serpents are, how full of deadly poison: and we have been reading how, by listening to the old serpent, the poison of sin--having our own will, and thinking hard thoughts of God--came into the hearts of God's creatures, bringing sorrow, and shame, and death with it. How beautiful that the righteous One in whom was no sin, and who come to take away our sins, should tell us that "As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up." The serpent of brass was not kept in Moses's tent; it was lifted high, for all to see it. God, who knew His people's sin, and had sent those fiery serpents to bite them, had Himself told Moses to make that serpent of brass, and those who were bitten had only to look at it and live. If they looked at their own hurt, or at each other, or at Moses--all was of no avail; but "it came to pass that if a serpent had bitten any man, when he beheld the serpent of brass, he lived." God--who knew that every one of us born into this world is born away from Him, and with the dreadful poison of sin, like the serpent's bite, in us--gave His only begotten Son to be lifted up, that "whosoever believeth in Him should not perish, but have everlasting life." And He tells us to look at Him and live, just as the poor sinful people, dying of the serpent's bite, looked at the serpent of brass, and their deadly wound was healed. God has told us to look straight to His Son, dying for sin, dying in our stead; but it is not our looking that saves us, it is the blessed Saviour whose name is called Jesus, "for He shall save His people from their sins." I must not forget to tell you that many of the extinct animals whose skeletons are to be seen in museums belonged to the class of Reptiles. We read that "God created great whales"--or sea monsters--and remains have been found of enormous lizard-like creatures. One has been called the Fish-lizard; it seems to have had a crocodile's head, with a body like that of a small whale. Another had a long swan-like neck, the body and tail of a quadruped, and paddles like a turtle.
