A word of warning

As a young Christian, I was very struck by some words of J.C. Ryle, the ‘Evangelical Bishop’. I think that his passionate call to ‘fight valiantly’ still needs to be heeded today:-
I fear much for many professing Christians. I see no sign of fighting in them, much less of victory. They never strike one stroke on the side of Christ. They are at peace with his enemies. They have no quarrel with sin. – I warn you, this is not Christianity. This is not the way to heaven.
I often fear much for those who hear the Gospel regularly. I fear lest you become so familiar with the sound of its doctrines, that insensibly you become dead to its power. I fear lest your religion should sink down into a little vague talk about your own weakness and corruption, and a few sentimental expressions about Christ, while real, practical, fighting on Christ’s side is altogether neglected. Oh! beware this state of mind.
