It's always sad when I see the word Christian refer to anyone who doesn't obey Christ's primary command that we love one another. Jesus emphasized the importance of forgiveness stating that if we don't forgive He won't forgive us.
Forgiveness is subjective. We don't all agree on what is a mistake and what isn't a mistake that requires forgiveness.
Jesus destroyed the institutionalization of human interaction and left us with a simple principal that is hard to practice.
We are to love each other as much as we love ourselves.
I am both male and female as we all are. I've recently learned that I have to start the process of love by practicing loving self talk with both parts of me.
