At different times and by different means, we have been called into world missions. Our desire is to pioneer where extremely few are laboring. As Paul said of Turkey, "But now no longer having a place in these parts" (Rom 15:23a, NKJV), there is not much room for us here in America; we desire to labor where there is no church.
This being said, we have been invited to labor among a people that is .01 percent reached. That is even less churched than Iraq or Iran.
