Marriage is purely an institution from the divine(God). That is why a carnal man will not make the right choice. Whenever marriage is in question, the notion of a carnal man for the things they cannot do for themselves. Some people get married out of lust. Lust has been a central thing in the mind of people , which they often do mistake to be love. When a young man sees a lady, and feels attracted to the lady by the virtue of lust,it is not heaven's yardstick for the right partner.
That is why on the long run, when they might have gotten what they feel is attractive and getting feed up with it, they resort to promiscuous. An increased rate of adultery is seen here and there because even after they might have met the girl,they will still see someone else who will have the same features they admire in the previous one, and seen to be lost then.
Again, they go for financial gain. The primary aim of marriage is not for financial gain. The primary aim of marriage is not for financial, and this is one truth people have failed to know. Most ladies when choosing a partner will device their own yardstick, that the man must have this or that, or have this or that investment before they will agree to get married to the person. This is one reason people do make wrong choices in marriage, forgetting that when the right man and woman come together, their beginning may be small but their latter end will be great. Again, some families get so much addicted to a particular people that they do say to themselves, "My son must marry from this place". They tell their family member, "you must get married to this class of people". During the time of creation there was never a set pattern like that. I laid people up in different forms; I bring people together no matter the tribe.
Most mothers and family members have contributed immensely to this particular problem. The couple in question, when they might have come together, being faced with a particular challenge, will be left at the crossroad. And the family members that led them to the mess will be no where to identify with their crisis. This is what people go through, when they make choices for themselves.
When I reveal my will to them in marriage and it seems to be someone from another religion, let them ensure that they bring the person to the Christian fold. It is always a means of taking them from darkness into light; for as many as will stay away from the worldly views and decide to follow my pattern and my leading, and remove all the idols in their hearts to follow the way I direct; my grace, my power, and my strength will be sufficient and will abide with them while they go the path of marriage.
