The Resurrection tells us that with God all things are possible and it validates the claims of Jesus.
Christ’s Resurrection shows us that his promises are always kept even when we think they cannot or will not be kept.  An unknown author has made a list of "Our Thinking verses God’s Promises.” This list helps us realize that our thinking is not always correct when it comes to the what the Lord can do:
