Here we have, I. The displeasure which these hypocrites conceived against God for not accepting the services which they themselves had a mighty opinion of (v. 3): Wherefore have we fasted, say they, and thou seest not? Thus they went in the way of Cain, who was angry at God, and resented it as a gross affront that his offering was not accepted. Having gone about to put a cheat upon God by their external services, here they go about to pick a quarrel with God for not being pleased with their services, as if he had not done fairly or justly by them. Observe, 1. How they boast of themselves, and magnify their own performances: "We have fasted, and afflicted our souls; we have not only sought God daily (v. 2), but have kept some certain times of more solemn devotion." Some think this refers to the yearly fast (which was called the day of atonement), others to their arbitrary occasional fasts. Note, It is common for unhumbled hearts to be proud of their professions of humiliation, as the Pharisee (Luke xviii. 12), I fast twice in the week. 2. What they expected from their performances. They thought God should take great notice of them, and own himself a debtor to them for their services. Note, It is a common thing for hypocrites, while they perform the external services of religion, to promise themselves that acceptance with God which he has promised only to the sincere; as if they must be accepted of course, or for a compliment. 3. How heinously they take it that God had not put some particular marks of his favour upon them, that he had not immediately delivered them out of their troubles and advanced them to honour and prosperity. They charge God with injustice and partiality, and seem resolved to throw up their religion, and justify themselves in doing so with this, that they had found no profit in praying to God, Job xxi. 14, 15; Mal. iii. 14. Note, Reigning hypocrisy often breaks out in daring impiety and an open contempt and reproach of God and religion for that which the hypocrisy itself must bear all the blame of. Sinners reflect upon religion as a hard and melancholy service, and on which there is nothing to be got by, when really it is owing to themselves that it seems so to them, because they are not sincere in it.
