The Lord prospered the work in and around Periyamalai. Through Radio broadcast, missionary challenge meetings and songs, the missionary vision gripped the hearts of people. By December 1970, the friends came together for prayer and became burdened about the unreached frontiers of North India. The second milestone was reached in 1971 when missionaries set their feet in North India and the first mission field in North India was opened at Basti in Uttar Pradesh. Though FMPB had its origin in Tamil Nadu, it has emerged as a multi ethnic organization having its wings spread across the length and breadth of the Nation of India.
Its ministry in the unreached frontiers begins with a survey. It leads to opening of mission stations in receptive areas, preaching the Good News, teaching the believers, planting Churches, appointing elders, raising Evangelists, training the native leaders and strengthening the Church to become self-supportive, self-governing and self-propagative. And then to incorporate the worship groups of believers to the neighboring established churches and move over to other unreached areas.
