This is a nation which has been profoundly affected by Christianity, and this effect has been conspicuously displayed in London. Schools, hospitals, the welfare state, universities, reformation, revival and countless works among the poor has established London as a world beacon to which the world has looked for centuries. Whilst many through history have sought to change the world, no movement, no institution can be considered to compare with the effectiveness of Christianity. When the world asks how this was done - how it is that a religion that follows the teaching of a crucified leader can have made such an impact - repeatedly it finds the same answer - the faith of Christians in local churches.
