Although Christianity is necessary to saving The West; and Christianity must come first - before any programme of political, economic, or social changes; that does Not mean that we can or should use Christianity as a 'means to the end' of saving The West.
The situation is that we must have spiritual Christianity first, because otherwise we will not know what to do, nor how properly to do it.
To put is another way, without a spiritual Christian revival, The West will not be especially worth saving.
This is harsh but true. All that was good about The West will be lost - as much of it already has been lost, and indeed inverted, unless we first recover our spirituality.
