Offenses are painful. They can be very annoying. But no matter how painful or annoying the offense is, we must always forgive.
We will forgive because God commands us to do so. As the children of God, we must obey this commandment of God and always forgive one another. We must cultivate a habit of always putting away offenses from our hearts through forgiveness.
Let our forgiveness be total and genuine. Let it be sincere. Let us have true love for each other. Let us forgive without reservation. We should not call to remembrance the offense that people do to us. Let our hearts have love for others.
Why it is difficult for people to forgive each other is because they do not walk in love towards one another. We can forget about good things but we find it difficult to let go of evil things from our minds. This is because we are not walking in love. When we walk in love, it will be easy to forgive.
