Paul calls us to “keep before [us] an outline of the sound teaching [we] hear from him.” He tells us to “guard the treasure put into our charge, with the help of the Holy Spirit dwelling within us.”
The sound teaching of Paul is what we must guard — this is a treasure beyond compare. Paul is able to say this because he knows that his teaching is directly from God. He meets the resurrected Jesus on the road to Damascus. He travels to the “third heaven.”
What a weight! No wonder God allows a “thorn in the flesh” to keep Paul humble.
Paul also knows that “among [sinners he] stands first.” He says, “But I am mercifully dealt with for this very purpose, that Jesus Christ might find in me the first occasion for displaying all His patience, and that I might be typical of all who are in future to have faith in Him and gain eternal life.” (1 Timothy 1: 15 – 17)
Paul is telling us, “If I am saved, then anyone can be saved.”
Jesus says it a bit differently, “With men it is impossible; with God, all things are possible.”
Here is the good news – the gospel of Jesus Christ; this is the treasure we must guard.
