Children are the heritage of God and a blessing to any family that has them.
Here in Africa it's not easy to be married and not have children, especially for the lady who might face issues from her in-laws.
It's kind of you to wish this for all the childless people and I say amen to your prayers.
Africa is not like western world where some people can choose to stay without having children. It's really heartbreaking to see these women go through a lot.
