I believe one has to really know God in order to know what FORGIVENESS really is. If our Lord and Savior can forgive "us", and "you", then you have no reason not to. Get to know him, he will make your life so much easier! ;)
This is the day which the LORD hath made; we will rejoice and be glad in it. One of my favorite verses in the Bible. No matter how bad the day before might have been, each new day is an opportunity to start fresh. Rejoice and be glad in it!
