“Imagine you are on a high cliff and you lose your footing and begin to fall. Just beside you is a branch sticking out of the edge of the cliff. It is your only hope and seems more than strong enough. How can it save you?

If you’re certain the branch can support you, but you don’t actually reach out and grab it, you are lost. If instead your mind is filled with doubts and uncertainty that the branch can hold you, but you reach out and grab it anyway, you will be saved. Why?

It is not the strength of your faith but the object of your faith that actually saves you. Strong faith in a weak branch is fatally inferior to weak faith in a strong branch.”

—Timothy Keller, The Reason For God (New York, NY: Dutton, 2008), 234
