Answer:
To begin with, we need to understand how the Bible took shape, and when it was produced. The original book of the Bible refers to the Old Testament. The Israelites, that is, the Jews, only called the Old Testament the Scripture. And then, in the Age of Grace, the Lord Jesus did a stage of work of redemption. More than three hundred years after the Lord, church leaders of the time came together to convene a meeting. They believed that the last days were approaching and that the words the Lord Jesus had spoken, and the epistles that the disciples had written, ought to be summed up together to form a book similar to the Old Testament, and sent to churches in all places.
