Wow. I thought this was good! (Maybe it's just me...)
"In our natural life our ambitions change as we grow, but in the Christian life the goal is given at the very beginning. The beginning and the end are exactly the same, namely, our Lord Himself.
We start with Christ and we end with Him... not simply our own idea of what the Christian life should be. The goal of the missionary is to do God's will, not to be useful or to win the lost. A missionary is useful and does win the lost, but that is not the goal. The goal is to do the will of the Lord." ~ Utmost for His Highest, 9/23
Sometimes I get caught up in being "useful" to God and that's when I get into trouble.
