Matthew Henry's Concise Commentary

15:1-19 The people make a solemn covenant with God. - The work of complete reformation appeared so difficult, that Asa had not courage to attempt it, till assured of Divine assistance and acceptance. He and his people offered sacrifices to God; thanksgiving for the favours they had received, and supplication for further favours. Prayers and praises are now our spiritual sacrifices. The people, of their own will, covenanted to seek the Lord, each for himself, with earnestness. What is religion but seeking God, inquiring after him, applying to him upon all occasions? We make nothing of our religion, if we do not make heart-work of it; God will have all the heart, or none. Our devotedness to God our Saviour, should be avowed and shown in the most solemn and public manner. What is done in hypocrisy is a mere drudgery.
