“I have not hidden Your righteousness within my heart; I have declared Your faithfulness and Your salvation; I have not concealed Your lovingkindness and Your truth from the great assembly” (Psalm 40:10 NKJV).

David wrote this psalm to the Lord, writing of his own record of “declaring” the “righteousness, faithfulness, salvation, lovingkindness, and truth” of God before all Israel and to the surrounding peoples. His motivation for writing of his own public witness seems to be that he wanted the Lord to remember it as He considered David’s prayer requests. Surely David was not making a false claim, for the Bible often records his public declarations of God’s great character. Yet, this passage is truly fulfilled in the prophetic office of the Messiah, Jesus Christ.
 
Can you make the same claim as David? Do you “declare” the things of God before the people? Or have you “hidden” the gospel within?
