Congratulations on your becoming a church elder. May I share something? It has occurred to me that elders may often be tasked with counseling troubled married couples. So, here are some things that God has laid out concerning marriage.
“The heart is deceitful above all things, and desperately wicked; who can know it? I, the Lord, search the heart, I test the mind, even to give every man according to his ways, and according to the fruit of his doings.” Jeremiah 17:9-10.
