1 Thessalonians 2:2-3 (HCSB)

On the contrary, after we had previously suffered, and we were treated outrageously in Philippi, as you know, we were emboldened by our God to speak the gospel of God to you in spite of great opposition. For our exhortation didn’t come from error or impurity or an intent to deceive.

     Paul speaks quite boldly here and we cannot escape the import of his words.  “Our exhortation didn’t come from error or impurity.”  This is quite a claim to make, but one that he backs up again and again by pointing out that he is an apostle, that he has seen, The risen Lord, that his gospel was approved by the pillars of the church.  Paul is not preaching and teaching error, but the truth of the gospel.
     Expositors Bible Commentary:  First to be corrected was the claim that his appeal arose from “error” or self-delusion. Planes (“error”) at times has an active sense of “deceit,” a meaning indistinguishable in the present verse from dolo (“trying to trick you”). Here, however, it should be assigned its passive meaning of “error” as usual in the NT. Paul’s message agreed perfectly with truth.
     We would do well to emulate Paul as we teach and preach and communicate the gospel.  Accurate theology is important.
