Do not disagree.
You do not understand the arguement. I am saying When the law was given God struck up a contract that said if you follow the law all you will get is Health, Wealth, God's protection and a piece of the promise land. That's it. Nothing in the original contract says that if you follow the law you will receive eternal life.
Meaning Job and David could believe in a redeemer. The point I am making is that NOTHING In The Contract God made when He gave the law promised eternal life. You can't really argue this because the Sadducees who only worshiped God by the first 5 books of the bible, Say this. Remember this was what was taught in the temple by the sadducees during the time of Christ. They only believed in the Torah as being the inspired word of God. Remember the Torah where the books of moses/the first 5 books of the OT Which contain the law and the stipulations of God's original contract, and their whole form of worship based on the torah Conclusively says there is no after life.
One has to move outside of the books that contain God's covenant/contract and the law inorder to find scriptural support for the idea of an afterlife. Which is what the Pharisees did and what you are doing.
But again if you only look at the contract and the law at the time they where given and agreed upon.. Nothing even mentioned the idea of an after life let alone the promise of eternal life.
So following the law as a means to eternal life is a fool's errand. Even Jesus says so in John5:39
Remember even in the time of Jesus, the temple leadership taught that there was no afterlife. This was the primary difference between the pharisees (Temple minority) and the Sadducees (Official temple leadership.)
Actually the opposite is true.
The pharisees thought as you do that in the OT scripture can be found a path to eternal life.
Jesus point out this is wrong. He says the scripture points to Him as the only source for eternal life. What this means/How this is different than what you/the pharisees claim, is they thought that the OT laws; If you followed them, lead to eternal life. Jesus in John 5:39 is saying nothing in the OT scripture (Following the law) lead to eternal life.
39 You study the Scriptures diligently because you think that in them you have eternal life. These are the very Scriptures that testify about me, 40 yet you refuse to come to me to have life.
Again the point being is that the scripture rather the Old covenant/Old contract do not provide a path to eternal life. Only Jesus does. Which means before Jesus there was no a contractual path to eternal life through the law.
Now I understand what your knee jerk response will be.. You will want to quotes all of the passages in the ot and NT that point to eternal life. which is all fine and good but do not apply here. Why? Because all scripture point to what Jesus says here.. That HE alone is the only way to eterna life, that every scripture you will want to quote ultimately will go back through Jesus.
Meaning, before Jesus there was no contract between God and anyone else that said if you follow the law you will receive eternal life.
Now that said AFTER Jesus, there is a new contract, that does say we can inherit eternal life if we follow/believe in Him. But, again this is a new reward, new contract, new expectations.
