What is a claim?
Answering this has become so common and tedious that I place it here for reference.
The scoffer says, "I never made any claims".
What is a claim? It may be a propositional statement of truth, but not always. It may be a logical inference. It may be a scoff wherein you claim the thing scoffed is not true. The act of scoffing is such a claim. When someone says they own something because they bought it, that is a propositional statement claiming that there is more to existence than time, energy, mass and chance. Ownership is an attribute borrowed from God. He owns because he created.
If that person then scoffs at being owned by God, they have contradicted their previous claim. Their claim of ownership demonstrates Romans 1 which says that all men know that God is God. Ro 1:19 ¶ Because that which may be known of God is manifest in them; for God hath shewed [it] unto them.
