Charles H. Spurgeon on Psalms 34:8

O taste and see. Make a trial, an inward, experimental trial of the goodness of God. You cannot see except by tasting for yourself; but if you taste you shall see, for this, like Jonathan's honey, enlightens the eyes. That the Lord is good. You can only know this really and personally by experience. There is the banquet with its oxen and fatlings; its fat things full of marrow, and wine on the lees well refined; but their sweetness will be all unknown to you except you make the blessings of grace your own, by a living, inward, vital participation in them. Blessed is the man that trusteth in him. Faith is the soul's taste; they who test the Lord by their confidence always find him good, and they become themselves blessed. The second clause of the verse, is the argument in support of the exhortation contained in the first sentence.
