Every day will I bless thee ... - Compare Psalm 92:2; Psalm 55:17. As we receive blessings from God every day (compare Lamentations 3:23), it is proper that we should render to him daily thanks; as God is the same always - "yesterday, today, and forever" - it is proper that he should receive from day to day the tribute of praise; as we are daily dependent on him - one day as much as another - our recognition of that dependence should be daily; and as he will always be unchangeably the same, it will be proper that he should be praised forever and ever. Two things are apparent from this verse:

(1) that a truly religious man "will" worship God every day;

(2) that it is the fixed purpose of a truly religious man to continue this forever.

Every day will I bless thee,.... For new mercies had every morning; for fresh supplies of grace every day, which all come from the fulness of Christ, to whom all grace is given, and from whence it is received, and in whom all spiritual blessings are, and by whom they are bestowed;

and I will praise thy name for ever and ever; as long as he lived in this world, and to all eternity in the world to come. David understood the doctrine of the saints' perseverance, and knew he should not be an apostate and blasphemer of the name of Christ, but a praiser of it as long as he had a being; and that his principal service, and that of all the saints in the other world, will be praise; not praying, nor preaching, nor hearing the word, and attendance on other ordinances, which will be no more, but adoring and magnifying the riches of divine grace, Psalm 104:34.

Every day will I bless thee; and I will praise thy name for ever and ever.

145:1-9 Those who, under troubles and temptations, abound in fervent prayer, shall in due season abound in grateful praise, which is the true language of holy joy. Especially we should speak of God's wondrous work of redemption, while we declare his greatness. For no deliverance of the Israelites, nor the punishment of sinners, so clearly proclaims the justice of God, as the cross of Christ exhibits it to the enlightened mind. It may be truly said of our Lord Jesus Christ, that his words are words of goodness and grace; his works are works of goodness and grace. He is full of compassion; hence he came into the world to save sinners. When on earth, he showed his compassion both to the bodies and souls of men, by healing the one, and making wise the other. He is of great mercy, a merciful High Priest, through whom God is merciful to sinners.
