In Matthew 5:21-48, Jesus cites six laws and precepts from the Old Testament. After each, Jesus says, “But I tell you.” He then teaches an even stricter moral principle. Is Jesus contradicting the Old Testament? Is He correcting the Pharisees’ interpretation? Is He giving a higher law for Christians?
There are many opinions, but I want to show you from the Bible the plain and simple answer to why Jesus said, “But I tell you.”
