Pastor points out the Old Testament's words, "Thus says the LORD," and compares them to the words of Jesus in the New Testament that say, "But I tell you." What does this tell us about who Jesus is? Pastor explores the "But I tell yous" as found in Matthew chapter 5 and we learn what Jesus calls us to. That call is to a changed heart, which can only happen when we come to faith in Jesus. God's call is personal! He wants to change each one of us by the shed blood of Jesus, the Son of God.
