Today, the 14th of Iyar, is Pesach Sheini. H”S told Moses that on this day the people who weren’t able to make the Sacrificial Lamb for Pesach because they where defiled or came late could make it up this day by eating Matzah. What this teaches us is that our Creator always gives us second chances in life. There is no such thing as giving up and thinking we are doomed. We can always make up for past mistakes by doing Teshuvah, returning to our essence.
