SUPERNATURAL PROSPERITY - How can one get it?

First of all, supernatural prosperity doesn't and can NEVER answer to Prayer and Fasting,it answers to 'Covenant demand'.
prosperity is a Covenant:
a Covenant is an agreement enacted by God and man, a Promise that God has made with man.

Genesis 8:22 NIV-
"22
As long as the earth endures,seed time and harvest,
cold and heat,summer and winter,day and night
will never cease."
