6 When We turn Our mind and Our heart to the supernatural blessings of the Church that are to be shared with those people whose souls have not yet been suffused with the light of the Gospel, there appear before Our eyes either regions of the world where bountiful crops grow, thrive, and ripen, or regions where the labors of the toilers in God's vineyard are very arduous, or regions where the enemies of God and Jesus Christ are harassing and threatening to destroy Christian communities by violence and persecutions, and are striving to smother and crush the seed of God's word. (9) We are everywhere confronted by appeals to Us to ensure the eternal salvation of souls in the best way We can, and a cry seems to reach Our ears: "Help us!'' (10) Innumerable regions have already been made fruitful by the sweat and blood of messengers of the Gospel "from every nation under heaven,'' (11) and native apostles, with the help of divine grace, are blossoming like new buds and are bringing forth saving fruits. We desire to reach those regions with Our words of praise and encouragement, and with Our affection. We also wish to give them Our instructions and admonitions, which are prompted by firm hope based on the infallible promise of Our Divine Master, that is contained in these words: "Behold, I am with you all days, even unto the consummation of the world.'' (l7) "Take courage, I have overcome the world.'' (l3)
