Do not equate bringing life into the world with just pumping out babies.
While it is a biblical command to be fruitful and multiply, we must not forget that we should care and nurture the life that we bring into this world, lest we be like animals, nay worse than animals.
Christ has demanded of us to be like Sons of God.
While it is part of their principle duty to bring life into this word and a childless woman is unfulfilled, it is unmanly to reduce women to the rank of birthing machines. We’re not rats, we’re made in God’s image.
