lol. Not every single one of the 613 mitvot apply to me. I am not a Levi, priest, male, property-owner, etc, so I need not worry about trying to keep those laws.
And I have to wonder if perhaps you have ever sinned in your life. If so I would suggest you just stop trying to be a Christian, yeah? That is basically what you are saying, right? That if I cannot be perfect I should just not even try. That is not the point of keeping the Law at all. The point is 1) it is commanded of us to keep the Law and 2) it does, in fact, bring me closer to God. The Law is not only about doing this or not doing that. It is about showing God how much you respect and honor Him by being willing to try every day to keep the Laws handed down by Him to man.
