Because of blessed families, the world can start to develop horizontally. Without them, the world develops only vertically. Peter was crucified upside down to indemnify Adam's reversal of the law of heaven and earth, but John did not die because he was the model for the Lord of the Second Advent. The family is the point where God's love can be connected to the earth's people. Therefore, the family becomes the standard for the realization of Heaven.
Holy matrimony is the work of fulfilling the course of restoration.
Blessed families must go the same path I walked, spitting up blood to cry out to God. After a great blessing, there comes a great migration. After 21 years of gaining children and all things, Jacob moved to Canaan. Moses, too, returned to Canaan. After Jesus' time, the Germanic tribes made a great migration.
