In showing the contrast between our comfortable, commonplace, human way of thinking and the lofty, spiritual way of living, Oswald Chambers makes the following profound statement:
The nature of spiritual life is that we are certain in our uncertainty, consequently we do not make our nests anywhere.
Certainty is the mark of the commonsense life: gracious uncertainty is the mark of the spiritual life. To be certain of God means that we are uncertain in all our ways, we do not know what a day may bring forth.
Immediately we abandon to God, and do the duty that lies nearest, He packs our life with surprises all the time. When we become advocates of a creed, something dies; we do not believe God, we only believe our belief about Him. Jesus said “Except ye … become as little children.” Spiritual life is the life of a child. We are not uncertain of God, but uncertain of what He is going to do next. If we are only certain in our beliefs, we get dignified and severe and have the ban of finality about our views; but when we are rightly related to God, life is full of spontaneous, joyful uncertainty and expectancy.
