Grades of Faith...
Faith is made of grades.
Therefore, be careful when you listen to anyone pretending to know what God wanted to say, or interpreting any of the Divine Books, for you might be more genuine than they are, but they will make you doubt and downgrade you.
Keep your relationship with God extremely intimate and don't bother explaining anything to anyone.
Let Him operate the miracles you asked Him for, just for you.
It is enough that you believe in them.
Dwell in your certainty and nurture it.
