Yes, it is Heaven for such servants

 Imagine the joy of being entrusted by the master with responsibility, stewardship, of his kingdom, of his goods? Such intimacy with the divine will.

And what would these Goods be that you refer to? Your teachings. Not Paul's. Not John of Revelations. Your teachings. And who has done that gospel jesus? Who has taken responsibility and administration of your goods? No one. Certainly not christians. Certainly not the church.
