As a student pastor, praying one evening about what I would preach on Sunday, I had a disturbing thought.
What if all I do for the rest of my life is teach the Bible to a small handful of people?
“God,” I said, “I don’t mind doing this for a while as I prepare for real ministry but for the rest of my life? This my life we are talking about; I want to do something exciting, different, make my mark in this world.”
That evening was a turning point for me; I surrendered and made an amazing discovery.
Trying to squeeze out of life what I want never satisfies. Real satisfaction, joy, and lasting excitement comes through surrender.
For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel’s, the same shall save it. – Jesus (Mark 8:35 KJV)
I encourage you to offer your bodies as living sacrifices, dedicated to God and pleasing to him. This kind of worship is appropriate – Paul (Romans 12:1 GW)
