"For ... we have many members in one body, and all members have not the same office" (Romans 12:4)
While there is only one way to become a true preacher, unfortunately there are many doors into the pulpit. One is to be endowed with what is sometimes called a "good pulpit presence." Many a tall Absalom whose commanding presence and sonorous voice mark him as a natural leader of men is attempting to speak for God when he has not been sent by God. His call is from the people instead of from the Spirit and the results cannot be but disastrous.
Others have become ministers from a genuine but altogether human love for mankind. These have a strong sense of social obligation which they feel they can best discharge by entering the ministry.
Of all wrong reasons for becoming a preacher this would seem to be the most laudatory, but it is nevertheless not a spiritually valid reason, for it overlooks the sovereign right of the Holy Spirit to call whom He will.
The church that is man-managed instead of God-governed is doomed to failure. A ministry that is college-trained but not Spirit-filled works no miracles. Things will get no better until we get back to the realized presence and power of the Holy Spirit.
