Marriage is one essential step in life either towards greatness or failure. Marriage can either promote partners to greater height or drop them beneath. Failure in marriage or unhappiness is common in marriage in our 21st century, I often ask myself the reason for divorce or unhappiness in a marriage is it due incompatibility of the partner or not enough time to setrotype d opposite sex or what?
As a youth to be successful in marriage I bring dis question to my nairalander.

How many years or months is enough for courtship to have a successful marriage?

I don't think it's by how many months or years but honesty, understanding and fear of God

Marriage is all about maturity of the mind and self conviction of the life contract one is entering. It's a life contract and no room for divorce, that is according to christian teaching in Matt.19:3-12. If you have any question after reading that portion pls put it up.
On courtship, ideally it shouldn't be less than 6 months and more than 2 years.

Good luck dear.
