What does
general revelation tell us?
¥Is there hope for God's mercy?
General revelation does not tell us.
We can only guess there might be from the very fact that God provided general revelation.
Something like the Ninevites did when Jonah brought the message of judgment: Jonah 3:9-10 (NIV) "Who knows? God may yet relent and with compassion turn from his fierce anger so that we will not perish." 10 When God saw what they did and how they turned from their evil ways, he had compassion and did not bring upon them the destruction he had threatened.
