Just a thought

Today was one of those days that I truly realize how I have messed up things and hurt people. It truly breaks my heart that I have done this and truly and deeply hurt those who I deeply care about. It has been through my actions/non-actions and my words that have hurt so very deeply. I know that I have also recived hurt from people's words and actions/non-actions. On a day like this, I'm reminded so much of God's grace and mercy. He forgives us and gives us grace even though we don't deserve it. It was also just a good reminder to me today, that He does truly love us, even when we mess up everything. So why do we do these things to hurt the people we care about? Thoughts?
