God never asked us to live the perfect Christian life on our own. Instead, He sends Jesus into our hearts to live the Christian life for us. The exchanged life means that I am dead with Christ and He is alive in my spirit to live HIs life through me. In this lesson we look at the climatic point in Jacob's life where he wrestled with God and God changed his name and gave him a limp. We are to walk with a limp, signifying that our will is broken and we are dependent upon God for everything.
