Jesus explained all things in Scripture concerning himself (Luke 24:25-27). The Bible is not a textbook for science or political theory or any side issue. It speaks about Jesus and provides what we need to grow as disciples.
Paul makes this clear in II Timothy 3:14-17.
Most of our problems interpreting Scripture come from twisting the words of the Bible to make them say what we want them to say! (II Peter 3:14-16).
