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 PiperMarriage is not absolutely for making children. But it is absolutely for making children followers of Jesus.
John PiperThe highest meaning and the most ultimate purpose of marriage is to put the covenant relationship of Christ and his church on display. That is why marriage exists. If you are married, that is why you are married. If you hope to be, that should be your dream.
John Piper
