Why does God choose us?

I live a wonderfully blessed life! I don't mean that I am rich financially, but I do mean that I am very blessed by God! In today's rough economic times, I still have, not just one but, two jobs that I absolutely love! I have a wonderful wife who loves me! We both have a vehicle that runs! We haven't had to miss any meals due to financial hardship! God has blessed me with wonderful friends! I could go on and on, but this morning I was wondering why me? Not the Why Me! that we scream at God when life is not going as we think it should. I am talking about the quiet "why me?" that we ask in wonder as to why God would choose a sorry sinner like myself to work for Him. He, the Almighty, All Powerful, All Knowing, Everlasting, Ruler and Master of the Universe reached down and saved my soul! Then, he chose to give me so very much to be thankful for! I pray that one day if I, like Job, am asked to suffer for the Lord in a very real way that I too will stand true to my faith in Jesus Christ. I just praise God that He has given me another day alive to serve Him, and I pray that I won't waste it!
