1 Peter 2:3

If so be ye have tasted that the Lord is gracious ; rather, if ye tasted . If ye once tasted the good Word of God ( Hebrews 6:4 , Hebrews 6:5 ), if ye tasted of the heavenly gift which comes through that Word ( 1 Peter 1:23 ), long after it that ye may g-row therein. The "if" does not imply doubt; the apostle supposes that they have once tasted, and urges them, on the ground of that first taste, to long for more. The first experiences of the Christian life stimulate God's people to further efforts. The words are a quotation from Psalms 34:8 , "Oh taste and see that the Lord is good!" This makes it less probable that St. Peter is intentionally playing, as some have thought, on the similarity of the words χρηστός and ξριστός . The confusion was common among the heathen; and Christian writers, as Tertullian, sometimes adopted it; Christus, they said, was chrestus, " Christ was good;" and Christians, followers of the good Master, followed after that which is good. But St. Peter is simply quoting the words of the psalm, and applying them to the metaphor of milk. It is possible that there may be an under-current of allusion to the Lord's teaching in John 6:1-71 . The Lord himself is the Bread of life, the food of the soul. The epithet χρηστός is not infrequently used of food (see Luke 5:39 ).
