The only parochial [church] activities which have any real justification are those which spring from worship and in their turn nourish it.
—Jean-Jacques von Allmen, Worship: Its Theology and Practice, 55-56
Worship is the only Christian activity which is an end in itself.
All evangelistic activities of the church have as their goal finding more worshipers for God; all edification activities of the church have as their goal making better worshipers for God.
“For I tell you that Christ became a servant to the circumcised to show God’s truthfulness, in order to confirm the promises given to the patriarchs, and in order that the Gentiles might glorify God for His mercy.” (Romans 15:8-9)
And what was the aim of God in this overflow of mercy for the nations?
The aim was worship. Romans 15:9: “In order that the Gentiles might glorify God for his mercy.” Notice: It’s not just that the Gentiles might receive God’s mercy or simply experience God’s mercy, but that they glorify God for His mercy. The aim of the gospel among the nations is not man-centered. Paul does not say, “Christ became a servant in order that the Gentiles might receive mercy.” He says, “Christ became a servant in order that the Gentiles might glorify God for receiving mercy.”
The ultimate aim of the gospel is God — God glorified for His mercy. Don’t fall short of the ultimate aim when you preach the gospel. Don’t just offer people mercy. Offer them the greatest gift: a merciful God, and that God glorified for His mercy. Human beings were made finally for God, not mercy. Mercy is a means not an end. Savoring mercy is not the end, savoring God for His mercy is the end.

The essential, vital, indispensable, defining heart of worship is the experience of being satisfied with God.
—John Piper, “The Pursuit of God in Corporate Worship”
If your heart is not amazed by the grace of God,
and your mind is not gripped by the truth of God,
and your sense of right and wrong is not permeated by the justice of God,
and your faith is not resting in the power of God,
and your imagination is not guided by the beauty of God,
and your life is not steadied by the sovereignty of God,
and your hope is not filled with the glory of God,
then the service of God will be what Paul calls works of the law, and not the fruit of the Spirit. Work for God that is not sustained by wonder at God is a weariness of the flesh. Priority Number One is the cultivation of hearts that stand in awe of God.
—John Piper, “The Sacrifice of Praise (Hebrews 13:8-16” (sermon)
