1. Either God can create a stone so heavy that he cannot lift, or he can't
2. If God can create such a stone, then he is not omnipotent
3. If God can't create such a stone, then he is not omnipotent
4 Therefore, he is not omnipotent — Yajur

My answer:

x=stone God can't lift

1. If God can create x then God defeats himself
2. If God defeats himself then He is omnipotent
3. If God can't create x then God can't defeat himself
4. If God can't defeat himself then He is omnipotent
5. God can either create x or not
6. God can either defeat himself or not
Therefore
7. God is omnipotent
