You should read the entire bible before posting your opinions on it for everyone to see.
You have no clue what you're talking about in terms of the old testament, it's messiah, or righteousness.
You can't even talk about righteousness if you running around promoting the f@ggy can version of the Messiah whom you refer to as Jesus.
And the old testament did not constantly prophecies a messiah who will clean our sins.
You really should read more. Only one man can absolve us from our sins and you have never worshipped him a day in your life. In fact, you don't even know his name!
And you're right, this is very simple, but the problem is you and most Christians are so ignorant, that simple concepts are lost upon your understanding.
Here's a clue to help simplify it even more, and this should help you to break the spell you're under.
The Hebrew Israelite messiah, and his people, the ENTIRE nation of Israel, were and still are NEGROS.
Now, prove me wrong, or tell me why that doesn't matter. Just remember when one is under a spell he or she loses their ability of accurate perception and judgement. So don't get scornful when you receive the true wisdom that you have skimmed over in the Holy writings of Ancient Israel.
