Which Scriptures?

Now these Jews were more noble than those in Thessalonica; they received the word with all eagerness, examining the Scriptures daily to see if these things were so. (Acts 17:11, ESV)

The Jews of Berea were examining the scriptures. Which scriptures were the Bereans examining? They were not studying Matthew, Mark, Luke or John; those had not yet been written. They could not have been studying Acts; it was not written either. So, what were they examining? Clearly they were checking what we call the Old Testament (Genesis through Malachi).

But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it 15 and how from childhood you have been acquainted with the sacred writings, which are able to make you wise for salvation through faith in Christ Jesus(2 Timothy 3:14-15, ESV)

What scriptures did Timothy learn from childhood? It cannot have been the New Testament scriptures. Many of them had not been written even when Timothy reached adulthood, and none had been written when he was a child. Clearly it was Genesis through Malachi that his mother and grandmother taught him.

Many people study parts of the Bible and do not find that it makes them “wise unto salvation.” Many people study the Bible and do not find that it makes them “complete and ready for every good work” (2 Timothy 3:16-17). Why? Because they do not study the whole Bible. They skip through the Bible studying only the parts they like, and find that they have not accomplished much.
Get to know the whole Bible. Then and only then will you know what it might accomplish in your life.
