I'm sure his family and friends will miss him - but having read the bio you posted: it seems he's an evolution-denying YEC, so I doubt that he is a great loss to Christianity.
Why is that?
If God had left the earth to form by itself., what stage of creation would we be at now?
He created a mature earth and all animals and mankind to be adult. Well it would be no point trying to put babies on gases would there?
If God can create a whole universe in 6 days then why can you not believe your evolution impossible? No new creation from nothing in how many years. That's right evolution stopped didn't it.
We can make up many things but evolution more impossible than creation.
