Take your everyday walking around, eating, sleeping, going-to-work life, and place if before the Lord as a sacrifice. This gives him permission to come in and change whatever it is he want to change about your life. In this manner you surrender total control over to the Lord Jesus Christ. It's like saying, "Lord. here I am. This is all of me. Take my life and use if for Your glory and the upbuilding of Your Kingdom.
From this point, or before this point, you must be have a receptive heart. A heart waiting to receive whatever it is he is going to ask you to do. A heart willing to obey. A heart that will ALLOW God to change you from the inside out.
Will your heart say yes...will your soul say yes...
