REASONS WHY MARRIAGE FAIL IN THIS MODERN AGE
The major reason why marriages are failing is because women are no longer submissive to their husband’s full stop.
This may sound like I’m against woman, not all I’m only here to help as a married man. In the light of 1Peters 3:1 it says wives should be in subjection to their own husband, that if any (the husband) does not obey the word of God (simply put if the husband is wicked, bad, immoral etc) they may without word or preaching, teaching, rebuke, shouting etc be won by the conversation or good  behavior of their wives. If you read down ward you will discover Sarah calling Abraham lord, so the onus is on the women.
If you check the marriages of the 90’s, 80’s, 70’s etc you will discover that woman of those days where very submissive to their husbands at all conditions. The men of those days are not more perfect than men of these days, infact they are worst, because then they could marry up to 2,3,4,5 etc wives and live in the same house and the women still submit to them, some or many are not even rich like men of today. So marriages are failing today because women are no longer submissive to their husband not that men are becoming bad or immoral, for mankind has always been bad and immoral.
This is what the enemy has succeeded in doing i.e. empowering women to disobey their husband and children to disobey their parents, that’s why some laws empowers children to disobey their parents and wives to divorce their husband easily.
May God give us submissive women in JESUS NAME AMEN.
