How do I break thru to an atheist who wants to find God/spirituality?

I see the point of just letting him be. However, he is happy that I have found God and spirituality and truly expresses the desire to do the same himself.

His life, the way it is now is not working for him. He is not at peace with his beliefs. He hungers for more and continues on with his searching.

I'm scared for him. I feel that if he doesn't find peace, it will ultimately destroy him and I don't want that to happen. I don't want to give up on him nor do I want to push my beliefs at the same time. I've gently introduced topics for him to explore, but I feel like he needs more thanwwhat I'm suggesting. I'm at a loss.

He is not at peace with atheism. That is what I'm trying to say. He wants more. I'm not sure how to help him find more. If he were at peace with it, I wouldn't be so worried. Atheism itself seems to make him want to be gone from life. Yes, he has seen a doctor for depression. He needs more.
