Charles H. Spurgeon on Psalms 81:13

Oh that my people had hearkened unto me, etc. God sometimes doth not mind his children when they cry, that they may hereby take occasion to remember how oft he hath cried and they have not minded him. Doth not the Lord cry out to his people of duty and they do not hear him? Doth he not complain here of this neglect, not only as a dishonour, but as a grief unto him? No marvel then if God let his people cry out of misery, and doth not hear them. The Lord shuts his ear that we might consider how we have shut our ears; yea, he shuts his ears that he may open ours. We are moved to hear and answer the call and command of God, though we find that he doth not hear nor answer our call and cry. If the Lord should always be swift to hear us, how slow should we be in hearing him, and while we have our desires, forget most of our duties. Abraham Wright.
