Should an increasing Muslim population cause concern?

As the result of a sermon preached by Pastor James McConnell the Northern Ireland headlines over the last couple of weeks have been dominated by the issue of Islam. In the sermon preached at Whitewell Metropolitan Tabernacle Pastor McConnell described Islam as heathen, satanic and 'a doctrine spawned in hell'. Pastor McConnell also made the comment that he did not trust Muslims because of their devotion to Sharia Law. Many hours of news, television and radio debate have focused on this controversy, with politicians and church leaders giving views both for and against Pastor McConnell's statements, some defending the right to free speech and the exposure of false doctrine, others denouncing it as a hate crime. The greatest debate and outcry has been caused by the references to whether Muslims can be trusted, comments which some have construed as inciting religious and racial hatred.
