This is the divine formula for marriage: For this reason a man shall leave his father and his mother, and be joined to his wife; and they shall become one flesh (Genesis 2:24). It can be put this way: leaving others, cleaving to your partner and becoming one flesh. The first stage is normally easy but the second and third stages are sometimes challenging and seem impossible.
To cleave to someone totally different from you and also having unity in mind and body is tough. That is where the real marriage love is tested. Marriage is for imperfect couples who must be willing to learn and compromise to contain the other. Marriage becomes so rough and tough when couples think they are perfect and are not willing to listen and analyse the partner’s point of view.
In all, the ability to overcome challenges in marriage makes it sweet. The ability to enjoy what you have comes from God. Trusting in God always make right things right.
