Psalms 147:1

Here, I. The duty of praise is recommended to us. It is not without reason that we are thus called to it again and again: Praise you the Lord (Psa 147:1), and again (Psa 147:7), Sing unto the Lord with thanksgiving, sing praise upon the harp to our God (let all our praises be directed to him and centre in him), for it is good to do so; it is our duty, and therefore good in itself; it is our interest, and therefore good for us. It is acceptable to our Creator and it answers the end of our creation. The law for it is holy, just, and good; the practice of it will turn to a good account. It is good, for 1. It is pleasant. Holy joy or delight are required as the principle of it, and that is pleasant to us as men; giving glory to God is the design and business of it, and that is pleasant to us as saints that are devoted to his honour. Praising God is work that is its own wages; it is heaven upon earth; it is what we should be in as in our element. 2. It is comely; it is that which becomes us as reasonable creatures, much more as people in covenant with God. In giving honour to God we really do ourselves a great deal of honour. II.
