Tzedakah is different than charity. Charity comes from the word charitus, which means heart. Tzedakah comes from the word tzedek, which means justice, so when you are giving tzedakah, you are not just making the world a better place by contributing to hospitals, synagogues, churches, or your favorite cause. You are in a position of bringing justice to the world, becoming as God-like as possible.
You probably never realized this, but God wants to partner with us so that we can establish his kingdom here on earth. Have you heard of the universal principal of receiving? This principal is simply that in order to receive, you have to share. According to the Jewish tradition, an act of charity has the ability to change even a negative heavenly decree. Charity is not just meant to improve the world and those around you. It may surprise you to learn that it mostly serves to improve ourselves.
You can also look at your body and think about how the blood flows and the fact that your body is in constant renewal. It is a miracle of creation happening within you every second of the day. This is something to be thankful for. Cukierkorn, Celso (2010-11-14). Secrets of Jewish Wealth Revealed (Kindle Locations 2831-2832). Kindle Edition.
