What is God looking for in the world? Assistants? No. The gospel is not a help-wanted ad. It is a help-available ad. Nor is the call to Christian service a help-wanted ad. God is not looking for people to work for Him but people who let Him work mightily in and through them: “The eyes of the Lord run to and fro throughout the whole earth, to give strong support to those whose heart is blameless toward him” (2 Chron. 16:9). God is not a scout looking for the first draft choices to help Him win. He is an unstoppable fullback ready to take the ball and run touchdowns for anyone who trusts Him to win the game.
