The Beginning of the Gospel of God
In the Old Testament there are hints that the gospel was coming, but it was not until Jesus came that the gospel of God was fully revealed for all. Take Genesis 3; there were two examples of the gospel shown in that chapter. First we see how God will deal with Satan in verse 15:
“…he shall bruise your head,
and you shall bruise his heel.”
: God proclaims that while Satan will inflict pain upon Jesus, the big picture is that it’ll be a minor incident in comparison to what Jesus will do to him; it’ll be the pain of a person stomping his foot on a serpent’s head. Looking past the pain of the heel, who would you say has been defeated? Satan, in Genesis 3, is introduced as God’s enemy and God declares that one day Satan will be fully defeated.
Then we see part of the gospel in verse 21:
And the LORD God made for Adam and for his wife garments of skins and clothed them.
: Here we see part of what Martin Luther called ‘The Great Exchange.’ Not only does God take our sin, he also clothes us with His own righteousness. God responds to the sins of Adam & Eve by killing an innocent animal and clothing their shame with his skin. The gospel was always hinted at in the Old Testament, but it was not yet fully revealed until the time of Jesus.
