Really now...reaching a bit are we?
What I refer to as "mouth" Christians always get flummoxed when asked for evidence of anything pertaining to God since they have zero personal knowledge of God. "Heart" Christians have only a sad smile for you since by your very question ("show me how that's real if I can't see or touch it")it is obvious you are still searching for that moment of enlightenment.
Faith is not something definable, but felt strongly by those who have found their way there.
I have often found religion to be more of an impediment to faith rather than a way to attain it.
One of my favorite sayings "Rejoice not against me, O mine enemy: when I fall, I shall arise; when I sit in darkness, the LORD shall be a light unto me." has more to do with losing faith but finding your way back, more to do with those "mouth" Christians and doubters such as yourself rather than tripping over something.
I feel for you, but it's your journey to make or not, there's no rule that faith must be found by all.
Free will is, to me, God's greatest gift to us.
Make of it what you will.
