Zacchaeus stood and said to the Lord. “Half of my possessions, I shall give to the poor and if I have scammed anything from anyone, I shall repay it four times over.” Luke 19.8
You just read the words of a contrite man. He confessed to the Lord Jesus Christ of his intentions to make restitution for his sins.
Restitution is good for man; it causes him to make good for damage that has been done to others. It is cold and heartless to damage someone, change their life for the worst and just walk away like nothing has happen.
Yet, many evil people do that. Such uncaring attitudes cannot exist any longer. If one does wrong to another, he needs to make good on the damage. God wants men to enhance each other; not tear each other down by making life miserable for their helpless victims.
If you have caused damage to another, do the right thing. Go and repair that damage. And the most important thing is never cause hardship in the first place.
