Humility in us allows God to work freely in other people's lives, nurturing them without manipulation or making them the issue. There is not a problem that God cannot redeem. Walk in purity in your relationships with others, realizing that God created this person, died for him, and loves him. He has a treasure in his soul that God cherishes. Marriages would be reconciled if we would live by this.
Marriage is a gift and it is to be used in service for the Kingdom of God.
Instead of holding on to our desires and our natural understanding, God wants us to keep our hearts with all diligence. Furthermore, nothing can be taken from us unless we give it, because we are operating in a Kingdom that cannot be moved. In any relationship, the Cross is the point of identification with the other person. Christ left the glory of heaven and humbled Himself to go to the death of the Cross. If we will humble ourselves to the Cross and give freely to each other, our lives and our relationships will be built upon a foundation that cannot be moved.
