Meaningful thank you gift for next chapter in life

I have someone in my life who has done a lot for myself, thousands of others, the community, healthcare system and are just a wonderful human being. They are soon retiring and I would love to get them a meaningful gift thanking them and giving sincere appreciation for all they have done for me, for others and wishing them luck, prosperity and happiness in their next chapter of life. Family and faith are very important to this individual.

What would an appropriate/thoughtful gift I could get them?

Thank you so much for any help you can provide. This person is the type of person that literally changes the world for the better.
