I recently studied Ephesians 4:17-24 with a group by listening to a message by Dr. Tim Keller. His focus was on the struggle of Christians to truly make Christ Lord in their daily lives. He described a teaching that made an impact on him during a college camp. Below is my transcription of what he describes in the sermon "The New Self."
"If the distance between the earth and the sun (92 million miles) were the thickness of a piece of paper,
Then the distance between earth and the next nearest star would be a stack of papers 70 feet high.
Then the distance between earth and the end of our galaxy would be a stack of paper 310 miles high.
And our galaxy is just a speck of dust in the part of the universe that we can see.
And if Hebrews 1:1-3 is right - that there is a God who created this and he holds it together with the Word of his power, with just his pinky,
Is this the kind of God you ask into your life to be your personal assistant?
Who are you living your life for? Who calls the shots in your life?
What a powerful message! It requires that I get serious about thinking about my relationship with God and what role he plays in my life. Dr. Keller goes on to describe some wonderful insights related to putting off your old self and putting on a new self in Christ.
