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.
How often have you witnessed to an unbeliever and had them challenge you by saying, “How can you be so arrogant to say that there is only one God – your God!”
Sometime after the creation of Adam and Eve on the sixth day of creation, see Genesis 1:26-31, they rebelled against God by eating the fruit of the tree of the knowledge of good and evil.
By doing so they brought sin into the world and upon all of humanity. The details of this are in Genesis 3:1-24.
