Some simple advice

So, a friend of mine is recently baptized as a born again christian. I think thats fantastic, and obviously dont think differently of him at all. The problem I have is he keeps asking me if I “would like to learn about Jesus.” Can anybody help me figure out a kind and respectful way to tell him that I’m confident in my faith and know about Jesus.

If this doesnt make sense I get it, it’s a weird situation.

Thanks
