Charles H. Spurgeon on Psalms 145:1

For ever and ever. To praise God now does not satisfy devout aspiration, for in this age the worshipper's devotion is interrupted by sin, fear, sickness, etc.; but in eternity praise will proceed in unbroken procession. —John Lorinus.

Verses 1-2. I will bless thee for ever and ever, and again, Ps 145:2. This intimates,

1. That he resolved to continue in this work to the end of his life, throughout his "for ever" in this world.

2. That the psalms he penned should be made use of in praising God by the church to the end of time. 2Ch 29:30.

3. That he hoped to be praising God to all eternity in the other world: they that make it their constant work on earth, shall have it their everlasting bliss in heaven. —Matthew Henry.
