John Gill

All thy works shall praise thee, O Lord,.... Not all his works or creatures in general; though these do objectively praise him, or are the cause rather of others praising him on their account: but those who are in a special manner the works of his hands, of his powerful and efficacious grace; when he has formed for himself, that they may show forth his praise; such as are a chosen generation, a royal priesthood, an holy nation, a peculiar people: these in an eminent sense, in the best way and manner, praise their blessed Saviour and Redeemer; see Isa 43:21; and thy saints shall bless thee: which are mentioned last, not as distinct from the former; but as explanative of them, as well as of their work: these are they that are set apart by the Lord, on whom his favours are bestowed; to whom Christ is made sanctification, and who are sanctified by his blood, and also by his Spirit; and, being sensible of the blessings of grace they receive from him, rise up and call him blessed, and ascribe blessing, honour, glory, and praise to him, for ever and ever.
