He had said, “Ask, and ye shall receive;” which sinners hearing might perchance say, The Lord herein exhorts them that are worthy, but we are unworthy. Therefore He repeats it that He may commend the mercy of God to the righteous as well as to sinners; and therefore declares that “every one that asketh receiveth;” that is, whether he be righteous or a sinner, let him not hesitate to ask; that it may be fully seen that none is neglected but he who hesitates to ask of God. For it is not credible that God should enjoin on men that work of piety which is displayed is doing good to our enemies, and should not Himself (being good) act so.
