When my wife and I bought our home, we had to submit a token amount of
the purchase with the escrow papers. It wasn't all that much. I think it was
around a $1,000 or so on a $73,000 home back in 1988.
Anyway; the token amount was called "good faith money" because it was
meant to guarantee our honest intent to purchase. Had we reneged on our
offer and backed out of the deal, escrow law at that time would've caused us
to forfeit the good faith money and we would've been out of pocket $1,000
with nothing to show for it.
The thing is: were God to renege on His promise to protect believers from
retribution by means of their trust in the purpose of His son's crucifixion, He
would have to forfeit the Spirit, i.e. God would have to let people keep the
Spirit with them no matter where they end up in the afterlife.
