Julien compared love to bungee jumping. The ability to find the courage to jumpa off a ledge despite being terrified of the outcome.
Will you fall? Definitely. But will your faith keep you safe? Yes... Most of the time. Just like the rope used in bungee jumping, sometimes it snaps. Sometimes your faith, like the rope, is weak and you hit the ground.
But, just like Julien said, the ability to find the courage to jump is an impressive feat and one should not be afraid to fall.
