JST, 1 Corinthians 7:29–33, 38.
29 But I speak unto you who are called unto the ministry. For this I say, brethren, the time that remaineth is but short, that ye shall be sent forth unto the ministry. Even they who have wives, shall be as though they had none; for ye are called and chosen to do the Lord’s work.
32 But I would, brethren, that ye magnify your calling. I would have you without carefulness. For he who is unmarried, careth for the things that belong to the Lord, how he may please the Lord; therefore he prevaileth.
