The notion of faith as mentioned in the New Testament is mostly an invitation to become brainwashed.
If you want any real assurance of the existence of a God or Gods then you need to turn to Philosophy first, and specifically to Aristotle and Aquinas.
Aristotle the ancient Greek philosopher tells us that with all the heavenly bodies in the night sky obviously in motion -- Sun, Moon, planets, comets, and meteors -- then there must obviously also be some Prime Mover who put them into motion.
This is an intuitive notion from Earth experience that nothing moves here either unless someone moves it, throws it, launches it, or flings it etc.
Aquinas adds 5 more "proofs of God" to the body of philosophical thought. One of these includes the Prime Mover argument as well.
So the good news is really that Philosophy indicates there must be a God or else everything else would not be here.
From this good news as your starting point, you or anyone else can then decide which of the current 12 major world religions you would like to choose to become your own specific faith-based system.
Your proof has come from Philosophy, and then your faith can focus on Religion.
