Psalms 66:1

I. In these verses the psalmist calls upon all people to praise God, all lands, all the earth, all the inhabitants of the world that are capable of praising God, Psa 66:1. 1. This speaks the glory of God, that he is worthy to be praised by all, for he is good to all and furnishes every nation with matter for praise. 2. The duty of man, that all are obliged to praise God; it is part of the law of creation, and therefore is required of every creature. 3. A prediction of the conversion of the Gentiles to the faith of Christ; the time should come when all lands should praise God, and this incense should in every place be offered to him. 4. A hearty good-will which the psalmist had to this good work of praising God. He will abound in it himself, and wishes that God might have his tribute paid him by all the nations of the earth and not by the land of Israel only. He excites all lands, (1.) To make a joyful noise to God. Holy joy is that devout affection which should animate all our praises; and, though it is not making a noise in religion that God will accept of (hypocrites are said to cause their voice to be heard on high, Isa 58:4), yet, in praising God, [1.] We must be hearty and zealous, and must do what we do with all our might, with all that is within us.
