Everything related to God depends on faith because we can’t prove otherwise that He exists.
That, though, I think is intentional. If God showed himself in person, performed miracles before you, raised a relative from the dead, then you couldn’t deny His existence. You would be forced to accept that he is real.
God, though, wants you to choose Him freely and not not by force. What good are people cowed by a physical demonstration of unspeakable and undeniable power? They’d only follow out of fear.
Rather, He wants a people who despite their doubts make a leap of faith to believe. Willing people who make a loving and free choice to believe.
It may be necessary that his existence remains unprovable in this world, since faith is the requirement for us to freely choose God.
