The movement is an effect. The great cause of this movement is the action of the Holy Spirit with His gifts and fruits worked through men and women, with a clear and broad vision of the need of lost souls, with a recognised spirit of faith and sacrifice, and a clean testimony; who, inviting the Great Missionary, our Lord Jesus Christ, place in the background all material, personal, religious, denominational interests, to give first place and priority to the supreme interest of fulfilling the Great Commission and the evangelisation of the world.
