You have a wife who has given you eight children? In my view, as someone who probably will never have any, you have been blessed by God.
Yes my wife of 34 years has given me 8 children. When I was an atheist I had no intention of having any kids. I got saved in the Army while in Honduras and that changed everything. Praise the Lord!
My daughter has miscarried twice and is in despair. I'm sorry if you are not able to have any.
