Acts 3:19, “Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord.”
If we look up the word repent in the above verse in NT Greek, we find the word metanoeo, which translates to:
“To think differently or afterwards, that is, reconsider (morally to feel compunction)”
To repent means to turn from or change your mind about something. We need to change our mind about our sin and forsake it. We need to confess it as sin, and ask God’s forgiveness for our failure, and we will be forgiven. God’s Word promises that when we confess our sins, He is faithful and just to forgive us of whatever we’ve done that was wrong. In other words, regardless of what you’ve done, if you will give it to the Lord, confess and forsake it, you can receive mercy.
1 John 1:9, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.”
