I have had the privilege to know this couple for many years. They have been a great demonstration to me of 1st Corinthians 13.
“Love is patient and kind. Love is not jealous or boastful or proud or rude. It does not demand its own way. It is not irritable, and it keeps no record of being wronged. It does not rejoice about injustice but rejoices whenever the truth wins out. Love never gives up, never loses faith, is always hopeful, and endures through every circumstance. Three things will last forever—faith, hope, and love—and the greatest of these is love.” v4-7,13 NLT
