The Madasus are missionaries to the 10-40 Window, located on the island of Saipan, CNMI. Saipan is a strategic location to reach thousands of Asians because it is closer to Asian countries. The Asian countries are a major part of the 10-40 Window.
Originally, the Madasus are from India. Joel was born in a Baptist preacher's family - Joshua Madasu, who is now with the Lord, and Stellah is born in a Baptist family, who have been members of a Baptist Church for a long time. Their desire is to serve the Lord.
