What happens after death to those not united to Christ by faith?
At the day of judgment they will receive the fearful but just sentence of condemnation pronounced against them. They will be cast out from the favorable presence of God, into hell, to be justly and grievously punished, forever.
John 3:16–18 and 36: For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son … Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on them.
