Peter describes the taste as “that the Lord is good.” That the Lord would have people once born of perishable seed (and hence finite as grass) to be born again through imperishable seed (so that they become heirs of an imperishable treasure, where God is “Father,” 1 Peter 1:17) is surely evidence of God’s “goodness.” The taste for that kind of nourishment and life is addictive! The string of words closing 1 Peter 2:3 also echo Psalm 34:8, where David (after his near-death experience with Abimelech) instructed his compatriots to “taste and see that the Lord is good.” The new lease on life (born again!) that David experienced prompted him to confess God’s goodness and drove him to instruct others to enjoy with him the sweet taste of God’s mercy.
3 if indeed you have tasted that the Lord is good.
