It's important to realize how much a gift each day is to be alive and be free.
I've lost a great deal of family to cancer. My father, however, survived it. If he hadn't, I may not be here today. But not everyone has had the mercy of G-d as my father had.
Recently, I had a former boss of mine pass away. This is the same boss who fired me at Sprint, who I mentioned in http://4life4freedom.blogspot.com/2014/07/goodbye-sprint.html had denied me my religious holiday request, and had threatened to retaliate against me, and my family as a result. This person threatened us with a loss of income because of his mistake. Nor did he care - and made it worse, through his threats.
I don't hold a grudge against him. I pray for the family he leaves behind - wife, and two children, one high school and one middle school age.
But of all the things done to my family, to my G-d, by this person of "Jewish heritage" (i.e. he doesn't personally believe), this was, in my opinion, the most irksome to G-d. I wonder if his rejection of the Most Holy ate at him until the last day before he ceased to be.
