Albert Barnes on Matthew 19:11

All men cannot receive this saying. The minds of men are not prepared for this. This saying evidently means what the disciples had just said, that it was good for a man not to marry. It might be good in certain circumstances, in times of persecution and trial, or for the sake of lab outing in the cause of religion, without the care and burden of a family. It might be good for many to live as some of the apostles did, without marriage, but it was not given to all men, 1Cor 7:1,7,9. To be married, or unmarried, might be lawful according to circumstances, 1Cor 7:26.
