"Every aspect of my life is to be lived for God’s glory
1 Corinthians 10:31: “So whether you eat or drink or whatever you do, do it all for the glory of God.”At first reading, this principle may appear something of a no-brainer. However, if taken seriously, we will find that no other principle is quite so counter-cultural and counter-intuitive as this one. This principle defines ‘me’ in relation to ‘Him’. It says that ‘me’ and my life is all about ‘Him.’ It is only about ‘me’ to the extent and degree that I relate to ‘Him.’ Even though the gospel assures me that there is no better place to be, my ego kicks and screams for self-identity...
If my life is to be lived for His glory, then I no longer occupy that defining place of sovereign rule in my life. He does. If my life is all about His glory, then that becomes the great, unchangeable principle against which everything—good or bad—is assessed."
