I love this statement. When I'm not sure what to say to praise God, I can always declare this statement. God IS Good. It's true and says it all. I like the word "IS" it is a state of being verb. It's a present tense and a verb is action. Meaning currently Good and actively Good. If I say God was good or will be good, then I am saying his goodness is finite. But to say He IS Good, that is infinitive. Never ending!
"Oh that men would praise the LORD for his goodness, and his wonderful works to the children of men!"
