Five Star Gift Ideas

One idea could be getting him a special, high-quality Bible or a book about Christianity that he may enjoy. Another idea could be to enroll him in a class or retreat related to Christianity or the Bible that he's interested in. You could also give him a piece of Christian-themed jewelry, like a cross necklace or bracelet, or a religious artwork that he could hang up in his office or study. Lastly, you could consider arranging a visit to a significant location or holy site associated with Christianity that he may appreciate.

Or you can get him a star map with the date when he was born.
