It is not always all about you. Things happen in life…some good…some not so good. Often what is perceived as a personal slight has no personal intention behind it. You could never know what another is dealing with in their life. A careless word or action could be just that. Forgive often. Pray for the person and move on with your life.
For it is written:
“For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins.”
