Rav Dessler brings a mashal about the spiritual progress and development of a tzadik versus a baal t’shuvah. The tzadik advances in his service of Hashem bit by bit, like climbing the rungs of a ladder. The baal t’shuvah, on the other hand, is like a cripple who doesn’t have the arms and legs with which to climb. From his lowly place, watching the raging waters rise up from below, he cries out for help. At that point, Hashem comes and raises him up to great heights.
