In the 18th century Susannah and Samuel Wesley had 19 children, several of which left notable marks on the world. Two of the Wesley children, John and Charles, brought the word of saving grace through Christ to tens of thousands. The Wesley name is well known.
Having someone to carry on the family name means a lot. When a family name is sure to die out because no male child has been born to carry it on for another generation, people feel troubled. They want to keep a name for themselves in this world.
Don’t hang on to this world for the sake of your family name. God chose His people Israel and carried the promise of a Redeemer through the generations of men and women, all with imperfect records, because He was making a name for Himself. There never was intent that we’d look down through history and hold high the names of Moses or David or Paul. Names like Luther, Wesley, Carmichael, or your own family name are not what we hold high either. You are a part of God’s family, and that’s the name that matters!
