For though I preach the gospel, I have nothing to glory of: for necessity is laid upon me; yea, woe is unto me, if I preach not the gospel! 1 Corinthians 9:16
Those who are truly sent by God are marked by the fact that they are faithful to the message of the Gospel, exalting the Lord Jesus Christ, proclaiming to men the good news of salvation through Him, and bidding men to turn from their sins and come to Christ as Savior and Lord. They back all of their proclamations by the authority of the Bible, the Word of God, and they call Christians to lives of holiness while they themselves are living examples of holiness. Unless a man is divinely sent to preach the Word, his ministry will be ineffective to produce faith and life in those to whom he ministers. God must do the sending. I always tell young men who ask me about entering the ministry that they should never become ministers if they can possibly help it. If a man could be satisfied as president of the United States, as president of a bank or a college, as a pitcher for a big-league ball team, or in another position of honor or distinction, he has not been called to the ministry. God has not sent him. When God sends a man there is a yearning, churning, burning inside him. Like Paul he must cry “Woe is unto me, if I preach not the gospel”. This must be the heart feeling of everyone who has been sent with the Gospel.
