In the New Testament, the Greek word for Repent is Metanoeite. It is coined from the words meta and noieo which means to think differently or to reconsider. Practically, it means to stop what you were doing before or to start doing what you were not doing before
The first public word that Jesus preached was “Repent” (Matthew 4:17). Without repentance there is no forgiveness of sins. In Acts 2:38, Peter, on the Day of Pentecost commanded his hearers to repent for the remission of sins. Further in Acts 3:19, he said, “Repent and be converted that your sins may be blotted out”.
This means a person can believe in Jesus Christ, be a worker in church and even a minister of the gospel but his name is not written in the Book of Life because he has not left his old ways of thinking and acting. His sins have not been forgiven and therefore he has not experienced salvation.
Jesus said that there is joy in heaven over one sinner who repents (Luke 15:10). If there is no repentance there is no joy in heaven because there is no salvation.
Finally, Jesus commanded to preach repentance.
"And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem."
Luke 24:47
We will do well to submit to the ideologies and commandments of our Lord Jesus Christ. Amen.
