Then came a violent squall of wind which drove the waves aboard the boat until it was almost swamped. Jesus was in the stern asleep on the cushion. They awoke him with the words, “Master, don’t you care that we’re drowning?”
And he woke up, rebuked the wind, and said to the waves, “Hush now! Be still!” The wind dropped and everything was very still.
“Why are you so frightened? What has happened to your faith?" he asked them. (Mark 4:37-40)
Do you catch the implication implicit in those questions of His? Jesus is saying that faith in Him - belief in the realities of who He really is - should cause us to become fearless. Because if there's a logic in His mind to "Why are you fearful; have you no faith?" then the inverse is almost necessarily true: "Ah, so you have faith; now you need not ever fear."
Really, we should all question any talk of "faith" in Jesus that doesn't exhibit proportionate growth toward fearlessness for His purposes. The better we know Him the riskier it should look. The disciples' transition between the Gospels and Acts is all the proof we need.
