Marriage is the union of a man and woman to become one for procreation and to fulfill the will of God. Marriage is to be sweet, pleasurable, fun, in fact, any good thing that you can imagine. No disadvantage in marriage because whatever the Lord made is meant to be perfect.
For I know the thoughts that I think towards you, saith the Lord, thought of peace, and not of evil, to give you an expected end .
Marriage is gold and like most precious metals you must invest time and resources to secure it and fashion it into a jewel of great price. If a man is not experiencing fulfilment in marriage, it is not because God did not create it to be fulfilling but because man has left God out of marriage.
What most people think is marriage is actually the ceremony called a wedding so they take their time planning for a wedding instead of their marriage. Wedding is just a party where the public gathers to witness the two individuals that are going into marriage together. Marriage comes after the party is over.
