Luke 3:8-14 (KJV)

1. Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham.
2. And now also the axe is laid unto the root of the trees: every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire.
3. And the people asked him, saying, What shall we do then?
4. He answereth and saith unto them, He that hath two coats, let him impart to him that hath none; and he that hath meat, let him do likewise.
5. Then came also publicans to be baptized, and said unto him, Master, what shall we do?
6. And he said unto them, Exact no more than that which is appointed you.
7. And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.

Acts 3:19

1. 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.

Many understand the term repentance to mean “a turning from sin.” Regretting sin and turning from it are related to repentance, but are not the precise meaning of the word. In the Bible, the word repent means “to change one’s mind.” The Bible also tells us that true repentance will result in a change of actions (Luke 3:8–14; Acts 3:19). In summarizing his ministry, Paul declares, “I preached that they should repent and turn to God and demonstrate their repentance by their deeds” (Acts 26:20). The short biblical definition of repentance is “a change of mind that results in a change of action.”
