Charles H. Spurgeon on Psalms 145:2

Praise. If we are to define it in words, we may say that praise is thankful, lowly, loving worship of the goodness and majesty of God. And therefore we often find the word "praise" joined with "blessing" and "thanksgiving": but though all three are akin to each other, they are not all alike. They are steps in a gradual scale —a song of degrees. Thanksgiving runs up into blessing, and blessing ascends into praise; for praise comprehends both, and is the highest and most perfect work of all living spirits. —Henry Edward Manning, 1850.
