Forgetting Sovereignty

How often we forget that God is sovereign. I was reminded of my own inability to remember while reading Müller's and Schönherr's Afterward to Dietrich Bonhoeffer's magical little Prayerbook of the Bible:

Christian prayer is not a natural self-expression directed at God, an uttering of spiritual needs, but rather a way to God. Only Jesus Christ can go this way...At its core, then, prayer is a praying along with Jesus ... Christians, then, do not pray as their own spirit and feelings happen to dictate. The Spirit of Christ in them teaches them how and why they ought to pray. (pp. 180-181)
