John's whole life was defined by his service to God and to God's Son. His clothing, his food, and his tasks were all defined by his mission—to prepare the way for the Lord. How could he live his whole life for someone else? He defined himself as unworthy to even be the servant or slave of this someone else, this coming one who is so much greater than he. Jesus comes to us and asks us in our day to let him define our lives as well. That's what it means to call Jesus Lord—we see ourselves as unworthy to be his servants and slaves; yet, because of his grace, we are called his brothers and sisters. For such blessings, we offer him our lives in service to him and his kingdom.
