One man asked Christ "what must I do to be saved?",jesus said "leave/sell all that you have and follow me"...the man walked away sobbing...
Jesus meant much more meaning within this event.He was asking the man to disregard the tangible and trust/follow christ.The man walked away because he could not bear the thought of this life being insignificant to the one christ has prepared...All because he couldnt see or touch it.
The above in no way attempts to show that what Jesus says exists is there...it simply means to trust him.Yes,I mean faith...
Try once,fail twice...
