I think none of us are worthy, but God has chosen some to be channels of truth to the world. I also think that we don't have to be too "wise...brave...strong...to endure it." I think we simply have to believe and be willing to share God's truth with those who need it. God chooses the "ignoble and contemptible things of the world...so that no flesh at all should be boasting in God's sight." I agree it could be frustrating to present the obvious truth to people only to be rejected especially if you do it more than once to some, but we have to remember that God chose some to have faith "before the disruption of the world" and will call them out of this world into the ecclesia, the body of Christ. I think we just need to be content to plant the seed, and let God make it grow. I know we want everybody to believe the truth when we get it because it is such a blessing, but I think God only wants some to be saved in grace through faith even though all will eventually be saved at the consummation of the eons. And I think there are many believers who just won't receive the revelation of universal reconciliation due to the intense programming of church doctrine, but they're still believers even though they don't understand the full scope of the evangel. So I'd say we should try not to get frustrated with the way things are going because God is "operating all in accord with the counsel of his will."
