To protect people from themselves, God drove them out of the Garden of Eden. But, it was also a logical consequence to the fact that they hd disobeyed God. We see something interesting, then, in this verse. We learnt hat Adam was driven to the ground from whence he was taken. As noted, Adam had been placed in the Garden. He was not made there originally. At all times, the great things God provides us are a gift. Even to Adam, who had been taken from some ordinary part and placed in Eden.
Notice, however, that nothing is said about his position with God. It didn’t change when he lost the blessing of Eden. In the same way, we lose blessings and rewards if we mess up once we are saved. But, we will never lose our salvation. God only required that Adam come forth to receive forgiveness. Then, God sacrificed that lamb, and clothed Adam and Eve. He never made them go back to their own, failed fig leaves.
