Albert Barnes Commentary Mark 12:37

"David himself calleth him Lord; and whence is he his son? And the common people heard him gladly." — Mark 12:37 (ASV)

The common people heard him gladly. The success of our Savior in his preaching was chiefly among the common or the poorer class of people. The rich and the mighty were too proud to listen to his instructions. So it is still. The chief success of the gospel is there, and there it pours down its chief blessings.

This is not the fault of the gospel. It would bless the rich and the mighty as well as the poor, if they came with equally humble hearts. God makes no distinctions among people in conferring his favors; and wherever there is a poor, contrite, and humble spirit—be it clothed in rags or in purple, be it on a throne or a dunghill—there he confers the blessings of salvation.
