All true theology should lead to doxology.
God has a plan for creation. His ultimate intention is for every person to praise and worship him, giving him the honor and glory that he alone deserves.
The psalmist put it this way: May the peoples praise you, O God; may all the peoples praise you. May the nations be glad and sing for joy, for you rule the peoples justly and guide the nations of the earth. May the peoples praise you, O God; may all the peoples praise you (Psalm 67:3-5).
We study God’s word — that is, we have theology — so that we can learn more about him; that knowledge should then lead to praise of God — that is, doxology. The more we know about God, the more we are compelled to worship and praise him, awestruck at his greatness.
One of the reasons for missions — for spreading the Gospel — is so that verses like Psalm 117:1 will become a reality: Praise the LORD, all you nations; extol him, all you peoples. As we share theology (knowledge) of God, that should lead to doxology (praise) of God.
