The chief motivation for missions should be the “You” praised, not the “peoples” praising. The chief motivation for missions, both for God and us, is not the love of man, but the love of God. If you have been blessed to know and enjoy all that God is for us in Jesus Christ, you will long as the Father does for every tribe , tongue, language, and people to praise the name of Jesus. For this psalmist, in desiring God, God’s desires have become his own. He longs for:
God’s way to be known v.2.
God’s saving power to be known v. 2
God to be praised vv. 3-5.
God to be delighted in as just v. 4
God to be delighted in as sovereign over all nations v. 4.
God to be feared v. 7.
Oh yes, missions should be done because we love people, but by first being zealous for God’s glory, we will love people more and we will love them best.
So yes, use resources like Operation World and Joshua Project to fuel your passion for nations by learning of the unreached peoples of the world, but the best resource to fuel missions is to dig into the Bible and discover how stunningly glorious your God is. In God you discover one so cosmically glorious all of the world must be wrapped up in praise.
“Missions exist because worship doesn’t. The ultimate issue addressed by missions is that God’s glory is dishonored among the peoples of the world. When Paul brought this indictment of his own people to a climax in Romans 2:24, he said, “The name of God is blasphemed among the Gentiles because of you.” That is the ultimate problem in the world. That is the ultimate outrage.
The glory of God is not honored.
The holiness of God is not reverenced.
The greatness of God is not admired.
The power of God is not praised
The truth of God is not sought.
The wisdom of God is not esteemed.
The beauty of God is not treasured.
The goodness of God is not savored.
The faithfulness of God is not trusted.
The commandments of God are not obeyed.
The justice of God is not respected.
The wrath of God is not feared.
The grace of God is not cherished.
The presence of God is not prized.”
