All the saints are alive in heaven. There are no dead in Christ in heaven. It’s “Eternal Life” not “Eternal Death”.
SURE they are!
CAn you REALLY not read?
2 Corinthians 4:14
... because we know that the one who raised the Lord Jesus from the dead will also raise us with Jesus and present us with you to himself.
DEAD people get raised.
EVERY one of your 'saints' died.
Ergo; they WILL get raised - EXACTLY like the Scripture says!
