Now when we talk about reasons for failure of marriages, we talk in terms of it's being unsuccessful and failing to meet up with the purpose as ordained by God
Meaning anytime a marriage can't fulfill what God has purposed it, it has therefore failed
I'm talking in terms of kingdom marriages
So,from the above explanation, failed marriage is not only when you you separate or fighting with each other but it's also when you fail to meet up with God's purpose for it
That's why one should marry in accordance to God's will and destiny. Immediately you fail to do so, your marriage is a failed one right from the start unless God's mercy finds you.
So many marriages that were done in church but honestly not recognized in heaven or in God's system
Hence the scripture, I will deny you that day on judgement Day
I'm still laying down the foundation
