Brothers and sisters in Christ, at the heart of all our praying must be a biblical vision. That vision embraces who God is, what he has done, who we are, where we are going, what we must value and cherish. That vision drives us toward increasing conformity with Jesus, toward lives lived in the light of eternity, towards hearty echoing of the church's ongoing cry, "Even so, come, Lord Jesus!" That vision must shape our prayers, so that the things that most concern us in prayer are those that concern the heart of God. Then we will persevere in our praying, until we reach the goal God himself has set for us.
