How is this relevant?
It's more like stepping foot [by faith] onto a "high-speed rail" and being assured of your destination-point. During the ride, you might decide to go against the "rules" of this rail, by standing on your head (thus likely needing the barf bag), hanging from the ceiling (thus bludgeoning the other nearby passengers in the head), sticking your arms out the windows (thus potentially loosing limbs), running up and down the aisle (thus hindering others and blocking any of the stewards/stewardesses [if there is such a thing on those rails, I've never been on one, lol]), taking up a whole row of seats as you spread out to lounge (thus costing others a seat and wasting space or making the old lady that was supposed to sit there, have to sit on Fred's lap)... [etc]
[Jesus = the "high-speed rail"... "I AM THE WAY" (NO "failure" there!)]
