Intrinsically? Nothing.
So it's a lottery?
I have always been amazed - not really - that the GRPL can hold on to its belief about predestination, yet can never explain away: Joshua 24:15 (New International Version) New International Version (NIV)
15 But if serving the LORD seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your forefathers served beyond the River, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the LORD."
How does one simply dismiss free will in light of this most unambiguous verse?
The question is not the call to believe, but the response. WHO will chose the God of Israel ? Well reading the OT we can see who it was .
By the way that quote is hung near my door as you enter. I have chosen to serve the Lord, because God so ordained that I do, Praise the Lord !
Why do people choose the way they do? Unless you have a clear cut answer from Scripture which explicitly excludes the Reformed view, you do not have a "most unamgiguous verse."
Ahhhhh...but as xzins would say, when was Joshua regenerated?
The verse is unambiguous in saying that Joshua made a decision. However, it is silent on how or why he made that decision. The verse is silent on whether or not God had to regenerate Joshua before he was able to make that decision. All it says is that a decision was made.
