A good marriage is one that consistently puts the other first and chooses the couple unit. How well do you put the others needs first in communication, survival, emotional well being, etc.? This is a metric for all relationships. “and walk in the way of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God.”
The second portion I assert is choosing the couple unit. This is the wisdom part. Sometimes putting the other person ‘first’, I use human comparisons, may put the couple unit at risk. At times we will have to ask the other person to bend or put in more effort for the sake of the couple and the couples calling.
The constant call upon the married persons life is to choose and return to the other as a couple. This also helps decide on where time is spent in wisdom. We are called to love everyone. But time and resources are limited. After creating a marriage covenant we choose to love them first before others. They are the deciding factor (not their feelings but them as a person) in how our time is spent. All of this together is then subject to the purpose of the marriage before God.
The call on the couple is living out the Kingdom mandate. The terminology of ‘Kingdom mandate’ or ‘kingdom call’ is undermined by our separation of secular and sacred. The ministry to win souls and be in church is the sacred and eternal – everything else is temporary and secular. When this divorce within the Christian life takes hold of our psyche the only way a couple can be doing good for the Kingdom is in church ministry. Difficult to do when you already work a full time job. I argue the Kingdom call is supporting the other in whatever good work is before them in Christ. This may include activities together or encouragement for when they are apart. This is a broad simplification and is intentional. Live life well. The Christian walk is as simple as giving a cold cup of water to someone who is thirsty. So do good and enjoy what the Lord has given you.
