The temptation is easy to settle the question of being a preacher on the dead-level of business, expediency, and convenience.

It is the spiritual view of the eternal values as seen by Paul in this prophetic passage that will win and hold the noblest type of man to the service of Christ. Nothing else will really get its grip on him. Get into close grip with Christ, if He is tugging at your heart to put you into the ministry. If Christ puts you in, you will stay in and you will not be sorry, but count it your chief glory to have been counted worthy of that high dignity.

–A. T. Robertson, The Glory of the Ministry, p. 38.
