He not only makes us who we are but also brings us together. The joining together is not a one-time thing. It begins on the day when public vows are made, when sexual intercourse and oneness in that sense takes place, but it takes a lifetime to join people together. We grow together through laughter and struggles, through sorrow and thanksgiving. What God has joined together, no one should separate.
Marriage can be tough.
It involves living with a person who is a different gender, who has a different way of looking at things, who comes from a family that does things differently. The beautiful thing is that God takes people who do not automatically connect and teaches them to draw one another out. You will never understand yourself better than when you see yourself through the eyes of someone who loves you intimately, who probes, asks tough questions, and cares about stuff we don't even see in ourselves. It is an extraordinary thing, and it requires faith. God is committed to marriage.
