Suffering is not only the consequence of completing the commission, but it is God’s appointed means by which He will show the superior worth of His Son to all the peoples. Just as it was “fitting that He...should make the founder of [our] salvation perfect through suffering” (Heb. 2:10), so it is fitting that God save a people from all the peoples from eternal suffering through the redemptive suffering of Jesus displayed in the temporal sufferings of His missionaries.
