What is the worst sin of all of them? The Torah has 613 commandments, regulations and ordinances, so with all of those rules there would be (at least) 613 sins we can commit.
Of course, being the inventive and ambitious species we are, I am certain that humanity has found new and wondrous ways to have violated every single one of those commandments.
Yet, we still always want to know who is “Number One”, don’t we? Who’s the best boxer? Who is the best pitcher in baseball? Who was the greatest President? So naturally, we would want to know which sin is the greatest; not that any sin is great, but which sin is the worst one anyone can commit?
I am thinking that the worst sin would be the one that violates the most important commandment, leaving us now to wonder which is the most important commandment, right? That is, fortunately for us, easy to answer, since Yeshua Himself told us- it is to love the Lord your God with all your heart, soul and might.
Therefore, since loving God is the most important commandment, the worst sin would be to not love the Lord. But how do we know we don’t love God? So many people shout it out at services, or say they do all the time, but how do we know if we really love the Lord?
Oh, wait- that’s pretty simple, too, because the Big Guy gave us that answer, as well: obey Him. That is in Yochanan (John) 14, when Yeshua said that if His Talmudim (Disciples) love Him, then they will obey His commandments. Now, the trick here is to know that Yeshua never gave them any commandments because there is nothing “New” in the New Covenant writings. Everything Yeshua told His Talmudim they should do came directly from the Torah.
So, what do we have? The answer to the question, “Which is the worst sin of all?” is the sin that violates the most important commandment of all, to love the Lord. And how do we show that we love the Lord? We obey His commandments. All of them, which are the ones Yeshua (Jesus) told us to obey, the ones He taught, which encompass every single one of the 613 commandments found in the Torah.
That’s it. Simple, straight-forward, easy to understand. If you want to commit the worst sin of all, just disobey God. It doesn’t really matter which commandment you disobey, you have 613 to choose from, just don’t make excuses. Don’t try to tell God that you love Him but you reject some of what He says because you don’t agree, because you think they aren’t important, or because your Rabbi, or Priest, or Pastor, or whatever told you that the commandment was done away with. Yeshua says in Matthew 5:17 that He didn’t come to change the law. If anyone tells you that the laws of the Torah have been changed, or aren’t valid anymore (gee, if they aren’t valid doesn’t that mean they’ve changed?) then you are being lied to.
Don’t be left thinking that you don’t really love God because you still sin. All of us sin, and many, many, many do love the Lord. . God understands that, and since He can look into your heart He can see the love that is there but which cannot overcome the Yetzer Hara, the Evil Inclination, which we all have.
That is why He sent Yeshua.
I think the worst sin that anyone can commit is to reject Yeshua, the one who came to overcome the sins we cannot overcome ourselves. There is nothing in the Torah that commands we must accept the Messiah: we are promised a Messiah, we are told what to expect, what He will do and why God is sending Him. But there is nothing that says, “Thou shalt accept my Messiah and follow Him.” Maybe because accepting the one to save us from ourselves is so basic, so understandable, that it is considered a Prima Facie fact of existence. After all, who wouldn’t want to be saved?
Now that’s a good question for which I have no answer.
