Question:
Is it true that we shouldn’t make up theory, and then find Scripture for it?

Answer:
Yes, we should not have a firm conviction before studying to see what the Scriptures say. We shouldn’t have a conviction first and then try to find a Scripture to support it.

It is OK though to take a theory and search the Scriptures to see whether it is so (Acts 17:11). It happens a lot that people want to believe something badly enough that their minds are already made up; then they may try to find a verse to support it. We need to rightly divide the truth and believe whatever the Scriptures say (1 Timothy 2:15).
