When I was a young man I thought Paul was making too much of his call. I did not understand his purpose. I did not then realize the importance of the ministry. I knew nothing of the doctrine of faith because we were taught sophistry (deception) instead of certainty, and nobody understood Spiritual boasting. We exalt our calling, not to gain glory among men, or money, or satisfaction, or favor, but because people need to be assured that the words we speak are the words of God. This is not sinful pride. It is holy pride.
