And yet jesus fulfilled the law and preached the gospel of grace. Did jesus create a grey area?
In my opinion it's not the word of the law but the details that need to be addressed.
The appointed times and the preparation of them are of the Lord.
The 4 gospels are very Jewish. In order to understand what's taking place and how profound some things seem it is necessary to study what we refer to as the old testament.
No, Jesus did not leave a grey area.
And the truly important, nay, essential parts are crystal clear.
But the earliest church members werent fully aware how to act, or they were acting in ways they thought was ok, but Paul, like the corinthians, had to let them know some of those things were not good.
He never said you would lose your salvation. He never said dont talk to unbelievers, in fact Jesus commanded us to. But he did say not to associate with them regularly.
But he talked to themm in a way they understood, via their culture. It is not possible to write one book in which the details are accurate in all languages and cultures. So many of the details are hard, or impossible to figure out. So learning as much as we can about the jewish culture, like reading the OT, helps
an example is, native aborigines in australia dont understand the concept of owning land. they dont even have a word for it. So, when they read things like the aforementioned lot that Judas bought, they dont understand what that means
