I have found this analogy to work great when witnessing to people who intellectually know the truth about Jesus but refuse to accept it. I took this analogy from John MacArthur’s Bible commentary on the book of Hebrews. (pg. 86)
Let’s say if there was a fire in a hotel and you are on the tenth floor. Because there is a net below, the firemen are yelling, “Jump.” But you do not jump. You hesitate. You are well aware of the danger and know the net is your only way of escape; but you do not act on what you know is true and necessary. You might be concerned about saving some of your possessions, or perhaps you think that somehow you can find another way out. You might also be afraid of being hurt from the fall. Some might even be concerned about how they would look while jumping – afraid of embarrassment. But the point is this: simply knowing about the danger and knowing about the way out of it will not save you. If you do no jump you will die. When your very life is at stake, nothing else should matter.
