All Torah is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work. (2 Timothy 3:16-17)
Of course, the text actually says “Scripture” (or graphe in Greek), but I believe we forget that the Torah was the primary document Paul had in mind when he penned those words.
Could most believers today unreservedly affirm that the entire Torah is profitable for reproof, for correction and for training in righteousness, i.e. equipped for every good work that God prepared beforehand for us to do? I think most of us would hem and haw, cough and sputter, provide caveats and addendums to Paul’s declarative statement.

Nate, this is a good start to get people–especially Church people–thinking, and introduced to God’s Torah.
However, as one who now has 13 years of Messianic experience under his belt, I would personally put “Tanach” in place of “Torah.” For many of my Messianic colleagues, their Bible ends with Deuteronomy, with the Prophets and Writings having little say in what they think or believe. As we both know, Paul held much more than “the Pentateuch” in high regard.
I think it would be awesome if we did more teachings in Isaiah, the Psalms, and those obscure Minor Prophets–among other things. Every book of the Tanach gives us a peek into the worldview of Yeshua and His Apostles.
FYI, Kaiser has some really good things to say about 2 Timothy 3:16-17 in his Promise-Plan of God!
Great point, John. The audience I had in mind was traditional Church people. But you’re absolutely right that we can’t repeat the mistake of the Sadducees.
