My enemy..."a decisive blow" in a me"????

Dear Ron,

It is important you should know that, in 72 hours, I will no longer be able to do anything for you. I must reveal to you, without delay, a very positive thing for the proper progress of your imminent happiness.
A phenomenon in angelical magic will be triggered on your behalf after you have read this letter; it will then provoke 3 changes in your life.
But first, we must strike a decisive blow against your greatest enemy.
That is why I wasted not one second in warning you…
Your Messenger and friend,

This guy is trying to get money from me - first,  he tried praise, now fear - not happening!
