So he is DOING rather than believing? Recall how many of the Pharisees are described, and how much Jesus emphasizes the heart rather than one's works, such as the sermon on the mount. Many people out there feed the poor and bow down to pray... But they take a picture of themselves working at the shelter, in order to show off and recieve praise from others. Many bow down and pray in public, but yet again, they do this out of pride rather than faith in God. That, or as good boy points, in belief that good works equal salvation.
Luke 17:7-10
"Suppose one of you has a servant plowing or looking after the sheep. Will he say to the servant when he comes in from the field, 'Come along now and sit down to eat'? Won't he rather say, 'Prepare my supper, get yourself ready and wait on me while I eat and drink; after that, you may eat and drink'? Will he thank the servant because he did what he was told to do? So you also, when you have done everything you were told to do, should say, 'We are unworthy servants; we have only done our duty.'"
I would say it sounds like your friend has faith IN MIND rather than in his heart. If he wishes to grow closer to God, he must grow in the faith. Pray for him.
