There is no evidence that proves that the Torah taught to Adam, Noah and Abraham and given through Moses to the Israelite Nation on the way to Sinai and before the sin of the golden calf has become obsolete and irrelevant. On the contrary, man is still judged by this standard and God has never repudiated any promise or covenant that He has ever made with His creation.
We have created a gospel that has taught many people to believe, that you can become a Believer and not follow Yeshua.
There is a great deal of difference between what this world offers and the promises of God!
The sinner is not redeemed because he repents,
but he is called upon to repent because he has been redeemed!
Yeshua and the disciples preached a message called "the Gospel of the Kingdom." Matt 9:35 says,
"And Yeshua went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the Kingdom..."
It is related to, but not the same message as, the gospel of personal salvation that is generally preached today. In preaching the Gospel of the Kingdom, there was no appeal to join an organization which men might designate by various denominational names. It was an appeal to "repent," to change one's belief system from one thing to another. Men were and are either building kingdoms of man or the Kingdom of God. The Gospel of the Kingdom presented the appeal to believe in (have trust in) God and to build and promote His Kingdom, by making disciples. Matt 28:19,20
"Therefore, go and make disciples of all the nation in my name, teaching then to obey all that I commanded you. ..."
(This rendering of Matthew 28:19,20 is similar to the reading of the Shem Tov Hebrew manuscript and the Greek manuscript Eusibius quoted before the Council of Nicaea. )
