Calvin has already established his understanding of "a twofold government" to which human beings are subject: an inward government in which God rules over the individual human soul for eternal life and an outward government in which God through human government establishes civil justice and outward morality (4.20.1).
Marriage has been instituted by God, but it is not a sacrament. Many are the good things which God has instituted, but that does not make them sacraments, which are, by definition, signs and ceremonies to confirm God's promise to us. The fact that marriage illustrates Christ's relationship to the church does not make it a sacrament either - many are the things that illustrate it, but they are not sacraments.

(Rev. 1:17, 18)
There are many challenges that a young Christian husband faces in the first years of marriage. There may be doubts about his ability to be a good dad when the time comes. There may be temptation to see and gain worldy success immediately in order to provide the best life for his family. There may be struggles in figuring out how to balance work, family, church ministry, and leisure. But perhaps the greatest challenge of all is to understand rightly the Biblical instruction for his role as a husband in leading and serving his wife.
Romans 8:29 For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. 30 And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.
