“because only He knows the future.”
How would you go about proving this statement?
I mean, you’re trying to establish a FACT based on FACTS, right? Submitting evidence for a conclusion.
But if you’re talking facts, you have to be talking facts all the way. Not opinion.
This statement only works for people that:
1) already believe in gods.
2) already believe in YOUR god.
3) already accept The Bible as the product of THAT God.
4) already believe the future is limited to God’s psychic powers, not anyone else’s. But, while witchcraft is outlawed, Saul did use witchcraft to talk to the dead, right? So, other powers that don’t come from God are biblically possible.
You have to prove only your god can provide such prophecy.
Which would require that you prove your god exists.
Which means you can’t use prophecy to prove your god exists until you establish that prophecy requires god.
