The Bible was not created in a vacuum. It was built over millennia by God’s direct inspiration to people who had lived in those times.
While it’s not a requirement to understand more about the Bible for the sake of salvation or serving, we are responsible to sharpen our understanding to the degree we’re gifted with brainpower. If for nothing else, it keeps smart people out of trouble.
