Verse 21. To declare the name of the LORD in Zion, and his praise in Jerusalem. Great mercy displayed to those greatly in need of it, is the plainest method of revealing the attributes of the Most High. Actions speak more loudly than words; deeds of grace are a revelation even more impressive than the most tender promises. Jerusalem restored, the church re-edified, desponding souls encouraged, and all other manifestations of Jehovah's power to bless, are so many manifestoes and proclamations put up upon the walls of Zion to publish the character and glory of the great God. Every day's experience should be to us a new gazette of love, a court circular from heaven, a daily despatch from the headquarters of grace. We are bound to inform our fellow Christians of all this, making them helpers in our praise, as they hear of the goodness which we have experienced. While God's mercies speak so eloquently, we ought not to be dumb. To communicate to others what God has done for us personally and for the church at large is so evidently our duty, that we ought not to need urging to fulfil it. God has ever an eye to the glory of his grace in all that he does, and we ought not wilfully to defraud him of the revenue of his praise.
