You've been lucky, Huw. Lucky to suffer and lucky to spend these weary months in bed. For so God has given you a chance to make the spirit within yourself. By prayer, Huw. And by prayer, I don't mean shouting, mumbling, and wallowing like a hog in religious sentiment.
Prayer is only another name for good, clean, direct thinking.
When you pray, think. Think well what you're saying. Make your thoughts into things that are solid. In that way, your prayer will have strength, and that strength will become a part of you, body, mind, and spirit. The first duty of these new legs is to get you to chapel on Sunday.
