V1: 5. Who have sinful natures ? All mankind. How was this seen ? ; β€˜ In Cain, who slew his brother. Why did he kill his brother ? Because he was jealous of him. What do we mean by sinful natures? Hearts opposed to God. How do we show it? By our sinful thoughts and acts. What do we all need? A new heart. | How may we obtain it? By believing on the Lord Jesus Christ. What will this do for us ? It will bring us back to heaven and happiness. ; GENESIS, 4.
