1. JESUS told Peter that if he wanted to catch fish to fish off the Right side of the boat. Peter changed over to the Right side and caught fish. He had caught nothing on the Left side.
2. JESUS told the fishermen to cast their nets off the Right side of their boat. They changed to the Right side and could not pull their net back into the boat because of the number of fish in it. Their nets had come back empty from the Left side.
3.Also, in the Bible it says that the heart of the wise inclines to the Right and the heart of the fool inclines to the Left.
