In an article on The Islamisation of the West Dr. Patrick Sookhdeo of the Barnabas Fund writes,
Governments and the public must be made aware of the danger of allowing Islamist activists to take over Muslim organisations and claim to represent all Muslims. The excessive demands of Islamists must be rejected, along with their blaming of host societies for all the difficulties faced by Muslims. It is important that democratic Western societies do not give up their hard-won heritage of equality before the law, freedom of expression and freedom of religion. It must also be made clear that tolerance must work both ways and that threats of violence are unacceptable. Muslim communities must try much harder to isolate and expose Islamists who reject integration and the violent radicals among them.
For Christians the growing Islamisation of the West can be seen as both a challenge and an opportunity to sharpen our thinking and renew our evangelism. As we Christians see Muslim zeal, commitment, and willingness to sacrifice, we should be driven to repent, to pray for revival and act boldly for God in this generation. We need to stand firm on our Biblical foundations, beware of compromises and reach out in love to Muslims, offering them the Gospel of salvation in Christ.
