“Missions is not the ultimate goal of the church. Worship is. Mission exists because worship doesn’t. Worship is ultimate, not missions, because God is ultimate, not man. When this age is over, and the countless millions of the redeemed fall on their faces before the throne of God, missions will be no more. It is a temporary necessity. But worship abides forever.
Worship, therefore, is the fuel and goal in missions. It’s the goal of missions because in missions we simply aim to bring the nations into the white-hot enjoyment fo God’s glory. The goal of missions is the gladness of the peoples in the greatness of God. ‘The Lord reigns; let the earth rejoice; let the many coastlands be glad.’ (Pslam 97:1)
But worship is also the fuel of missions. Passion for God in worship precedes the offer of God in preaching. You can’t commend what you don’t cherish. Missionaries will never call out, ‘Let the nations be glad!’, who cannot say from the heart, ‘I rejoice in the Lord….I will be glad and exalt in thee, I will sing praise to thy name, O Most High.’ (Psalm 104:34; 92). Missions begins and ends in worship…”
John Piper (from the book Tell the Truth, p153)
“If people find worship boring and irrelevant, it can only mean they have no sense of the presence of God in it. When we study the action of worship in Scripture and the testimony of church history, we discover a variety of human responses to the sense of the presence of God. Some people tremble in terror, falling with their face to the ground; others weep in mourning; some are exuberant in joy; still others are reduced to a pensive silence. However the reactions may differ among human beings to the holiness of God, one thing I never ever find in scripture is someone who is bored in the presence of God, or someone who walks away from an encounter with the living God and says “that was irrelevant”.
There is no encounter a human being could ever have that is more relevant to daily life than meeting up with the living God. … You were not created to be bored by the glory of God, you have to be spiritually dead to be bored by the glory of God. ”
R.C. Sproul from The Holiness of God
