Two things with this:
1. Everyone who dies a believer will still live, not just the saints. What then, I can pray to my great-grandmother who died a christian? God forbid! Should I pray to any other mortal who died a christian? Should I split my prayers between God and dead men? Hell no.
2. Yes, the believers will be ressurected, but that comes at Judgement day after Armageddon. Until then, souls are only waiting:
And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. (Rev 20:11-12)
