It doesn't matter who you have hurt, if you've learned not to hurt again. It doesn't matter what mistakes you've made as long as you don't make them again. As long as you learn, as long as you're willing to take your life in your hands, and kiss it and go from there. Then there is growth. There there is life!
We are the people of life, because God, in His unconditional love, has given us the Gospel of Life, and we are called to act accordingly.
