Abstinence is a fine course of conduct among unmarried Christians.
Among Married Christians I'm puzzled why some oppose Birth control as a means of limiting the size of one's family, what is the religious reasons for that opposition?
Abortion is against Gods law! (Psalms 139:16;Exodus 21:22-25)
There's nothing wrong with marriage and having a big family if that what you chose to do and serving god.
I find it interesting the apostle Paul words at 1Corinthians 7:32-40
A large family, a small family with perhaps few if any children, or singleness along with chastity can be blessed by God as long as they all include service/ dedication to God.
In biblical times having a large family, specially one of males, was considered a great blessing. Now children are seen like a burden.
