In Chapter 3 (Discerning the Call) of his book If You Want to Walk on Water . . . , John Ortberg contrasts two very different approaches to re-visioning one’s calling: “The line between ‘Thou shalt not be afraid’ and ‘Thou shalt not be ridiculous’ is often a fine one and not easily located. Knowing when to get out of the boat and take a risk does not only demand courage; it also demands the wisdom to ask the right questions, the discernment to recognize the voice of the Master, and the patience to wait for his command.”
