“You search the Scriptures, because you think that in them you have eternal life; and these are they which testify about me.” (Jn. 5:39)
Everything in the Bible should be interpreted as a revealing a truth about Christ Jesus.
“For it is written in the law of Moses, “You shall not muzzle an ox while it treads out the grain.” Is it for the oxen that God cares, or does he say it assuredly for our sake? Yes, it was written for our sake, because he who plows ought to plow in hope, and he who threshes in hope should partake of his hope.” (1Cor. 9:9)
This clearly reveals that the Old Testament contains so-called spiritual sense. It says much about oxen and other animals, but this also has a spiritual sense that can help us.
“Now these things were our examples, to the intent we should not lust after evil things, as they also lusted.” (1Cor. 10:6)
“Now all these things happened to them by way of example, and they were written for our admonition, on whom the ends of the ages have come.” (1Cor. 10:11)
According to this verse the Old Testament was written in order to be a teaching example for us.
The following interpretation would be proclaimed incorrect by many theologians.
“Now the promises were spoken to Abraham and to his seed. He doesn’t say, ‘To seeds,’ as of many, but as of one, ‘To your seed,’ which is Christ.” (Gal. 3:16) The theologians would say “The word seed may mean a progenitor or progenitors according to our dictionaries, but in this context it means progenitors as is clear from the context.” But no, the Bible means what is says and should be taken literally, not based on man’s interpretation or what it seems to mean.
Don't follow every example in Bible. For example, you should not follow after the biblical example of Cain. “Woe to them! For they went in the way of Cain, and ran riotously in the error of Balaam for hire, and perished in Korah’s rebellion.” (Jud. 1:11)
