If a marriage is an example of The Mystery, then grace and peace have to be in the marriage. We see from this teaching God’s grace in the Church and how we as individuals can give that grace to our spouses. When we better understand that grace of God extended to us, it can help us extend that grace to others. We are shown examples of God’s grace in the Word, including the grace in Paul’s life. It also shows how grace and peace go together, so if we extend grace, we’ll see a lot more peace. We are to be imitators of God. He extends grace because He loves, and that’s the greatest motivation to extend grace, because you love. We haven’t earned anything, but God gives us grace.
