Peter says that God exalts those who humble themselves. This means that God lifts up and gives honor to people who have a modest or low opinion of themselves and their importance. These individuals recognize that they are not the center of the universe and that there are things greater than themselves. They are open to learning and growing, and they are not too proud to admit their mistakes or ask for help when needed. In doing so, they demonstrate a level of humility that God finds commendable, and as a result, God elevates them to a higher position of honor and respect.
