Glory to God Alone (1 Timothy 5:17-25)

As we walk through this world as human beings there is no doubt that we are tempted to live our lives to please man.  This is a real and honest temptation that we face, but why is that so wrong?  Why do we live our lives before the face of God?  Why is it so essential to live our lives before the face of God as His redeemed people?
