This psalm was to be sung in the Temple accompanied by instruments. It is a prayer, asking God to make Himself known to people everywhere. This prayer is consistent with God’s will and it is being answered today, perhaps even in this generation. Jesus has commanded us to go to the nations and make disciples (Matt. 28:19-20) and He also said that when every nation has heard the gospel, the end would come (Matt 24:14). So, we pray this psalm to God, knowing that only He can save and make Himself known, yet also knowing that we are called to be His heralds, announcing the gospel to the nations, so that they may hear and be saved.
