Does the modern age mean the end of faith? While some have argued that this is an age of total secularism, others argue that the times are far more religious than they may seem. The difference being that many people today have found ways of making their own religions. Not least of these is the cult of green: environmentalism. While the problem is not with protecting the environment, a good thing for Christians to care for, caring for the environment can very quickly become an idolatrous religion. In an age of many religions, Christians must be careful to guard their hearts and be faithful to the one true faith, once for all delivered to the saints.
