Jesus must have told people. This is such an important event that it had to be recorded in the Bible. Jesus proved that man is a being who is able to reject Satan and remain faithful to God in the most difficult circumstances. God had created such a wonderful being, yet Adam and Eve did not show this. But Jesus did! All glory to God!
God shows that he is a God of justice. He does not erase Adam’s guilt and failure, but allows it to be made right.
1 Then Jesus was led up by the Spirit into the wilderness to be tempted by the devil.
