Now, if that is what his problem is (and as I say, I dont know the man), that is a form of idolatry, because he is effectively saying that Christianity is not enough. It has to be value-added in some way. It is a very subtle temptation to all of us, and all the more dangerous when the bits added onto the gospel are in and of themselves very good things. I would suggest its very good for Christians to be socially aware. It no bad thing for Christians to want to make the world a better place. Its even ok for them to point out other people's errors - but none of those things are more important than the actual relationship with God that should be the foundation of a Christian's life.
So I'm quite sure he prays very regularly, and probably more than I do, but that doesnt matter if his prayers do not help in the transforming of his mind. If he has reached the stage where his social conscience and political outlook are his guide, and his prayers are only calls for God to rubber-stamp the decision he has already come to, he will derive little benefit from them.
I think you’re right. It’s a warning for all of us -— because all of us are similarly tempted.
