Charles H. Spurgeon on Psalms 147:1

David, to persuade all men to thankfulness, saith, It is a good and pleasant thing to be thankful. If he had said no more but "good", all which love goodness are bound to be thankful; but when he saith not only "good", but "pleasant" too, all which love pleasure are bound to be thankful; and therefore, as Peter's mother-in-law, so soon as Christ healed her of a fever, rose up immediately to minister unto him (Mt 8:15), so we, so soon as Christ hath done anything for us, should rise up immediately to serve him. —Henry Smith.
