If our prayers for you make you nervous, then perhaps you believe what we do deep within your heart, but you just chose to pretend you don't. If you truly didn't believe, our prayers for you would not have such an effect on your emotions.
Rest assured, that's not the case.
As for the other issue, the burden of proof here is on you. Name me one thing that is, in a tangible sense, permanent and everlasting. And I beg you, please don't say something trite like "Christ's love."
