Anglo, Jesus based Christianity: What if it’s all a lie and does not lead to Heaven?

O God, do not be silent! Do not be deaf. Do not be quiet, O God. Don't you hear the uproar of your enemies?
Don't you see that your arrogant enemies are rising up? They devise crafty schemes against your people;
they conspire against your precious ones. Come, they say, let us wipe out Israel as a nation. We will destroy the very memory of its existence. Yes, this was their unanimous decision. They signed a treaty as allies against you—these Edomites and Ishmaelites; Moabites and Hagrites; Gebalites, Ammonites, and Amalekites; and people from Philistia and Tyre. Assyria has joined them, too, and is allied with the descendants of Lot. Ps 83:1-8
