Prayer always turns our thinking upside down. Mary's song, the Magnificat, is the supreme example of this.
The fundamental meaning of prayer is that it is the way in which we invite God to take control and to rule in our lives, Edwards writes.
When God is at work he is never merely in the business of "adding his blessing" to what we have decided to do.
He wants to turn our unjust world upside down. He is a God who longs to bring down the arrogant and lift up the humble. He feeds the hungry and sends the rich away empty-handed.
We are always tempted to domesticate prayer. There is a deep desire in all of us to tame it so that we find it palatable and so that God doesn't disturb us too much.
But we dare not treat prayer like that. The fundamental meaning of prayer is that it is the way in which we invite God to take control and to rule in our lives.
True prayer, therefore, leads us on an adventure in which we participate with God in bringing about his amazing kingdom revolution.
I am glad that prayer has been at the heart of our conversations about the future of the life of the Baptist Union of Great Britain. We need to ensure that that continues to be the case.
The decisions that will need to be made this autumn about the future of the Baptist Union are immense. They will affect the way in which we work at all levels, and so we all need to take responsibility for praying in a concerted and regular way for our life together.
A one-off Day of Prayer, excellent as that is, is not enough. It would be great if you could set aside some time every Friday for praying for the Union, and I hope that the challenges and opportunities of the Union will find their way into your regular Sunday prayers. You will find many resources on the website to help you in this.
The challenges that we are all facing are vast. However, I am totally convinced that we can face them with peace and confidence if we commit ourselves to prayer.
We can be sure that it will involve a revolution, but what could be more exciting or more wonderful than sharing in a revolution in which God takes control?
