Men may be divided into two classes—those who have a ‘one thing’ and those who have no ‘one thing’ to do; those with aim, and those without aim in their lives… The aim in life is what the backbone is to the body: without it we are invertebrate.” How frightening it would be to be “invertebrate”—to be spineless, weak, and weak-willed—especially in the Christian life! But thanks be to God for these cherished-yet-instructive verses about the process whereby you and I may know and accomplish our “one thing”—attaining the great prize of the Christian race.

“Now you are the body of Christ and individually members of it. And God has appointed in the church first apostles, second prophets, third teachers, then miracles, then gifts of healing, helping, administrating, and various kinds of tongues. Are all apostles? Are all prophets? Are all teachers? Do all work miracles? Do all possess gifts of healing? Do all speak with tongues? Do all interpret?
