Unforgiveness can destroy us. God knows our heart of flesh can become hardened and lifeless if the wounds we have received are not allowed to heal. Jesus told all his disciples that we are to forgive others as we would like God to forgive us. In the workplace, there are people who look out for only themselves. Many times, their actions and attitudes can create in us something very unholy. We may find ourselves wishing the worst for them, secretly hoping that "they get theirs". This mindset of hatred and bitterness is one that can fester and build over the years as more and more people make your "list". The Word of God is clear – we are not to harbor hate, but we are to love our enemies and forgive their misdeeds. It's hard work, but it is what Jesus demonstrated for us; and then commanded us to do likewise.
