“In Old Testament times, this appellation was assigned to a person who had been entrusted with a divine office. Moses was called ‘the man of God’ (Dt. 33:1); David was called ‘the man of God’ (2 Chron. 8:14); Elijah was called ‘man of God’ (2 Kings 1:9); the prophets were called ‘men of God’ (1 Sam. 2:27) . . . in the above text [1 Tim. 6:11], however, the apostle has in mind young Timothy, who had been called to be the preacher and pastor of the church(es) in the city of Ephesus and its environs.”
