People learn in various ways but primarily through actually doing something repetitively. When we are young those log lines of letters and numbers that began as almost unrecognizable improve to make letters then words and so on. Our motor skills and muscle memory contribute to the handwriting we have as we age. The same thing happens with obedience, it may look or seem awkward at first, but the more we do it our obedience transforms into righteousness. Much like an eraser can remove mistakes on a page, repentance can remove sin from our life. The stain might remain but the correction is what we should be reading.
