great forgiveness, great faithfulness

I've been thinking allot about forgiveness and faithfulness and how those two things truly do go hand in hand. It seems like an obvious statement but I must be either slow or stupid because God has to keep reminding me, each time though bringing me closer to Him (which is probably His purpose for my short term memory problem!).
I just finished reading Luke. I've been reading through the gospels just trying to understand Jesus and how His importance should reflect in the way that I live my life. His humility through well thought out words really struck me this read through. My discoveries didn't end there as I decided to read through Acts. Everybody knows the story about Peter, how he denied that he knew Jesus three times and then a rooster crowed, just as Jesus said it would. As the rooster called Peter knew what he had done and Jesus looked him right in the eye. If thats not a sin that can't be worked through I don't know what is! But when I read Peter's word in Acts it struck me that Peter must have believed that He was forgiven of the denial of his dear friend and Savior right before His death as he was proclaiming the power of Jesus. This thought has given me great comfort in thinking about all the details that I don't know about such a big life change, and very soon at that.
God's forgiveness of my sins is testimony that He desires my best and will do whatever He has to to accomplish it. It was for Peter's own good that he denied Christ in such a crucial time (for another time, just think of how we deny Christ all the time yet it never seems as bad as Peter). I think you get the point.......I can sum this all up by saying that God is good and He will take care of me even during times of uncertainty.
