Could you give me your theological understanding concerning vasectomies?

Question from a reader:

Could you give me your theological understanding concerning vasectomies? We have 7 children. I realize that my body is not my own. I have been bought with a price. Therefore I want to do what Jesus wants me to do regarding this.

Let me first say, before I speculate, what I know for sure. As I’m sure you know, Scripture teaches that it is God that opens and closes the womb, and that children are a blessing of the Lord (Psalm 127). Reproductive fruitfulness is commanded and commended by God. Scripture knows nothing of the tragic bias often demonstrated today against people with large families.
