In Luke 24, Jesus says that "He suffered death, was raised, and that repentance and forgiveness of sins should be proclaimed in his name to all nations." His and the apostles teachings nearly always mentioned repentance next to faith. If it is so critical, then what does repentance mean exactly? The Greek literally means reconsideration or a change of mind. The change of mind is about sin and consequently a change of heart naturally occurs. For example, when I changed my mind about abortion, my heart ached at my past support of the murder of babies, leading me to change my conduct. In the same way every true Christian will experience a change of mind, leading to guilt over sin and so will begin trusting and obeying Christ.
May the Lord bring back preachers who will proclaim "repentance and the remission of sins" to America. It is currently the most needed and missing message.
