Jean Vanier said this quote

Flowing from this union, source of a plenitude of joy, the love of the couple reveals itself through the daily acceptance of the limits and faults of each other and in mutual openness. It is this acceptance in and through gentleness, kindness, forgiveness, confidence and the desire to see shining in the other the warm light of the Spirit of God that becomes the great sign of the merciful love of God for man and His incessant forgiveness.
