Mother Teresa also said: "If we really want to love, we must learn to forgive before anything else."
What a teacher. What a lesson.
To love, we must learn to forgive.
So, if you want to love, first learn to forgive.
That reminds me of Matthew 6:33 (my life verse), "But seek first His kingdom and His righteousness, and all these things will be given to you as well."
We must learn to do first things first.
