Christians, could Jesus take his physical body back at resurrection without invalidating his sacrifice?

If he was resurrected (especially if he knew he would be (which an all knowing god like him would)) than its not a real sacrifice. Ya I'd like to die for a few days too, so that my wife collects my life insurance and then I'm back and enjoy the benefit if dieing which I shouldn't because if I'm alive I don't deserve it. It's a scam. This means all our sins are not forgiven and were all going to Hell. Thank you Jesus for conning everyone during your life, and billions after you, and allowing people to use you to con everyone again, for their money. Thank you.
