The very first command of God to all of humanity was, “And God blessed
them, and God said unto them, Be fruitful, and multiply, and replenish
the earth, and subdue it: and have dominion over the fish of the sea,
and over the fowl of the air, and over every living thing that moveth
upon the earth” (Genesis 1:28). When Noah and his family came off the
ark God spoke again to all of humanity. He said, “Be fruitful, and
multiply, and replenish the earth” (Gen 9:1). Of course we must
reproduce in accordance with God’s laws, but as far as I can tell,
this command to humanity has never been repealed. The Bible also
says,
Psalms 127:3-5 Lo, children are an heritage of the LORD: and the
fruit of the womb is his reward.
4 As arrows are in the hand of a mighty man; so are children of the
youth.
5 Happy is the man that hath his quiver full of them: they shall not
be ashamed, but they shall speak with the enemies in the gate.
Psalms 128:1-4 Blessed is every one that feareth the LORD; that
walketh in his ways.
2 For thou shalt eat the labour of thine hands: happy shalt thou be,
and it shall be well with thee.
3 Thy wife shall be as a fruitful vine by the sides of thine house:
thy children like olive plants round about thy table.
4 Behold, that thus shall the man be blessed that feareth the LORD.
Psalms 107:41 Yet setteth he the poor on high from affliction, and
maketh him families like a flock.
Barrenness among God’s people was considered a reproach from God (Lk 1:25, Isa 4:1).
