Each must choose for himself. We may find the choice a hard struggle. Man's high destiny is to go to God, because man comes from God, and belongs entirely to God. Our reason tells us that Someone made us. That Someone is God.
Nothing can proceed from nothing.
If there had ever been a moment when nothing existed, nothing would ever have existed. Our reason also tells us that God must have made us for some purpose. God made man to know Him, to love Him, and to serve Him in this world, and to be happy forever with Him in the next. God made us for Himself. Whether he wishes to or not, man must manifest God's perfections, dominion, and glory.
