Walking on the water is easy to impulsive pluck, but walking on dry land as a disciple of Jesus Christ is a different thing. Peter walked on the water to go to Jesus, but he followed Him afar off on the land. We do not need the grace of God to stand crises, human nature and pride are sufficient, we can face the strain magnificently; but it does require the supernatural grace of God to live twenty-four hours in every day as a saint [one of God's chosen], to go through drudgery as a disciple, to live an ordinary, unobserved, ignored existence as a disciple of Jesus. It is inbred in us that we have to do exceptional things for God; but we have not. We have to be exceptional in the ordinary things, to be holy in mean streets, among mean people, and this is not learned in five minutes.
~ Oswald Chambers
