Charles H. Spurgeon on Psalms 150:2

Praise him acceding to his excellent greatness. There is required special understanding and knowledge of the nature and worth of the mercy for which the duty of praise is undertaken; for God will not be praised confusedly, but distinctly and proportionably to his dispensation: Praise him according to his wondrous works; which is to be the prime and proper matter of their high praises, even his more proper and peculiar high acts, then to be remembered, as is largely expressed in Moses' praise for the particular mercy of coming safe through the Red Sea (Ex 15:1-27); and Deborah's high praise for deliverance from the host of Sisera (Jud 5:1-31); where the chiefest and highest part of the celebration and exaltation of God in his praise consists in the declaration and commemoration of the particulars of God's special goodness in their present deliverance. Thus, you see the first thing that God looks for is proportionable praise, great praise for a great God, doing great things, and high praises for a high God, doing high things. —Samuel Fairclough.
