Much praying in these days misses the purpose of God on the earth. Our purpose was dramatically portrayed by the Spirit of God on the Day of Pentecost. Our prayers like the miracle of Pentecost should be aimed at the uttermost parts of the earth, at every “ethnos”  or people group on earth. World missions is the purpose of the church in the world. And Jesus said, This gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come. 
I have cancer. And that affects my prayer life. I am not interested in aiming my prayers at finding a better parking place at the Old Country Buffet. I sense the urgency to pray for the world.
