At the heart of creation was the creation of mankind, male and female, in his image. Adam and Eve, as the first created people, were given instructions by God in Gen. 2, but they disobeyed those instructions in Gen. 3. This is how sin entered the world.
Creation led to the introduction of sin into the world through the one man, Adam. It would seem that God’s plan was foiled immediately when the first created people disobeyed him, but that is not so. Just as God existed before creation, so God had a plan to conquer sin, even before creation. The first Adam points forward to the second Adam, Jesus.
“For as by a man came death, by a man has come also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive.” (1 Cor. 15:21–22) Adam and Eve brought sin and death into the world, which would seem to doom us. God can use even sin, though, as sin displays God’s plan of salvation to an even greater extent. The contrast of the second Adam with the first shows us even more fully the perfection of God’s Son in salvation. The second Adam, Jesus, brought resurrection from the dead. The second Adam, Jesus, makes alive those who were once dead in sin. Creation and the fall point us to Christ, just as the one who first sinned points us to the sin bearer who did not sin.
