RE: Verses that show everyone will go to heaven
It should be obvious that there are two eternal destinations.
(Romans 9:21-24 NIV) Does not the potter have the right to make out of the same lump of clay some pottery for noble purposes and some for common use? {22} What if God, choosing to show his wrath and make his power known, bore with great patience the objects of his wrath--prepared for destruction? {23} What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory-- {24} even us, whom he also called, not only from the Jews but also from the Gentiles?
(Matthew 7:13-14 NIV) "Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. {14} But small is the gate and narrow the road that leads to life, and only a few find it.
