There is the key. Not only did God make us, but He values us. God doesn't make junk. The Bible teaches that children are a blessing. God Himself is fertile.
Love always overflows into life.
The help of the Lord is essential, for He has dominion over human life and is its origin. Parents cooperate with God in bringing forth life. Because this whole process is under God's dominion, it is sinful to interrupt it. The Bible teaches that the child in the womb is truly a human child, who even has a relationship with the Lord. God knows the preborn child.
