“And Samuel said to Saul, Thou hast done foolishly: thou hast not kept the commandment of the LORD thy God, which he commanded thee: for now would the LORD have established thy kingdom upon Israel for ever” (1 Samuel 13:13). If Saul had been able to live a perfect life, if he had obeyed all of God’s commandments, then there would have been no need for Jesus to come and die for the sins of the world. Even though God made Saul another man and gave him another heart, Saul was still a man and he had a sin nature like everyone else. Even though I am born again and love God with all my heart, I still sin, I make mistakes and screw things up. That’s why I need Jesus, why you need Jesus, why we all need Jesus.
