Praying for my husbands relationship with Christ

Praying for my husbands relationship with Christ: My husband is at a place in life where he says he feels nothing. Nothing for me, nothing for life. He was once closer to God. But no longer believes in prayer or going to God when he is struggling in life. I believe a lot of his emptiness has to do with this. I just pray that God will open his heart and show Himself. Or that my husband will have a desire to get close to God and have a relationship with Him.
