Psalm 100:5 praises the LORD because He is good, His steadfast love endures forever, and His faithfulness continues through all generations. The verse describes God's own covenant character rather than directly predicting a personal trait of the Messiah.

Matthew 19:16-17 records Jesus responding to a question about what is good by directing attention to God as the ultimate standard of goodness. The textual wording varies among manuscripts and translations, but the passage does not explicitly cite Psalm 100:5. Christians confess Christ's perfect goodness on the basis of the New Testament as a whole, yet this particular connection should be stated as theological rather than predictive. Psalm 100 reveals the goodness of God; Christian Christology understands Jesus as fully sharing and revealing the divine character.
