“If any of your fellow Israelites become poor and sell themselves to you, do not make them work as slaves. They are to be treated as hired workers or temporary residents among you; they are to work for you until the Year of Jubilee. Then they and their children are to be released, and they will go back to their own clans and to the property of their ancestors. Because the Israelites are my servants, whom I brought out of Egypt, they must not be sold as slaves. Do not rule over them ruthlessly, but fear your God.” – Leviticus 25:39-43
Joy and forgiveness go hand in hand. You will not experience the joy that the Lord desires for you if you cannot forgive others. In fact you cannot even experience the forgiveness of God without forgiving your fellow man. (Matt 6:14-15) When you let go of a hurt it allows the joy and forgiveness of God to flow into that hurt and heal it.
May you find the joy of God in forgiveness!
