Send themselves to hell? Verse 18 says they are condemned already…
John 3:18 ESV
[18] Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
Psalm 81 lets us in on God's sentiments
8Hear, O My people, and I will warn you:
O Israel, if only you would listen to Me!
9There must be no strange god among you,
nor shall you bow to a foreign god.
10I am the LORD your God,
who brought you up out of Egypt.
Open wide your mouth,
and I will fill it.
11But My people would not listen to Me,
and Israel would not obey Me.
12So I gave them up to their stubborn hearts
to follow their own devices.
13If only My people would listen to Me,
if Israel would follow My ways,
14how soon I would subdue their enemies
and turn My hand against their foes!
15Those who hate the LORD would feign obedience,
and their doom would last forever.
16But I would feed you the finest wheat;
with honey from the rock I would satisfy you.”
God provides us space for repentance. What is that if it isn't love?
