God HAS a plan to shrink Islam and it's not as described in post 15.
His plan, already at work, is to send Christian missionaries to every Islamic country who move in the power and anointing of the Holy Spirit to show people the way to God through salvation in Christ, who pray for the sick, deliver the demon possessed, raise the dead, and train new converts to Christianity to carry on preaching the gospel, healing the sick, delivering those possessed by demons, and raise the dead, after the missionaries depart.
Show me where that has been successful, where there is a net increase in the proportion of Christians in any Mohammedan population. There are a few individual families here and there. There are many more converts to Islam in Europe and in America and especially in Mexico.
Christianity is not a system of government used to control people. It is God's working on earth through His Son, Jesus, and through the Holy Spirit, to bring others unto Himself.
The freeing and democratization of Islamic countries, I believe, is being used to open those countries to the Gospel.
I know that there is a temporary fleeing from Iraq of Christians because of the violence, but that will end, and the seeds of the Good News of Jesus Christ will flourish.
