God wants us to see beyond ourselves, our everyday needs, wants and desires to see the bigger plan. Have you ever noticed in the gospels when the Pharisees or the High Priests try to trick Jesus, he just redirect them.
I think it is natural for us to think same and see only our personal wants, but God wants more for us. Marriage is not about always doing what is right or wrong; it is an act of faithful and self-giving love. For the beginning God put together a man and a woman who were obviously both in need of grace.
There is hope for us. We don’t have to always get it right, we just have to allow the light of Christ to shine through our everyday, ordinary, and imperfect love. There will be times of struggle and doubt, but God always wants to lift our eyes to the greatness of his bigger plan.
