2 Corinthians 2:17
St Paul from the Trenches 1916
17For that is my position; it is a necessity to me to be all this, it is in utter sincerity that I stand before the world and speak the truth of the Christ as from God in the presence of God. I am not, and you know it, one of those so-called teachers who run round with the Gospel, dispensing it to people for a consideration.
