Our Lord does not promise to change life for us; He does not promise to remove difficulties and trials and problems and tribulations; He does not say that He is going to cut out all the thorns and leave the roses with their wonderful perfume. No; He faces life realistically, and tells us that these are things to which the flesh is heir, and which are bound to come. But He assures us that we can so know Him that, whatever happens, we need never be frightened, we need never be alarmed.
