All of history is moving toward one great goal, the white-hot worship of God and his Son among all the peoples of the earth. Missions 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.
John PiperThe wisdom of God devised a way for the love of God to deliver sinners from the wrath of God while not compromising the righteousness of God.
John PiperI do not appeal to you to screw up your courage and sacrifice for Christ. I appeal to you to renounce all you have to obtain life that satisfies your deepest longings.
John PiperSo you can see what is happening in the New Testament. Worship is being significantly deinstitutionalized, delocalized, de-externalized. The whole thrust is being taken off of ceremony and seasons and places and forms and is being shifted to what is happening in the heart - not just on Sunday but every day and all the time in all of life.
