Teach me how to give Grace

I was recently in a position where I was becoming bitter and unforgiving with someone that had in the past been a good friend.  I found myself feeling slighted, unappreciated, and even judgemental about the mistakes that person had recently made.  I felt like my feelings and actions were justified because of that person's mistakes.
Then another friend simply pointed out that I seemed too quick to be offended by anything and everything that happened even when it probably wasn't intended that way in the first place. I started praying about the situation and this is what I realized.
God gives us grace no matter what our mistakes. He died on the cross for our every sin, giving us Grace and Mercy for even the crimes we have yet to commit. I realized that only our own actions and guilt hold us back because he's given us a never-ending Grace and forgiveness and that I must strive to be more like him. I must learn to give Grace to others and love them through their mistakes. Grace is not earned or rewarded for good behavior. In fact it is given in spite of bad behavior. So this weeks prayer I am praying is for the Lord to teach me how to give Grace to others and show them how to be more like Jesus.
