The prophet Malachi said, “Didn't the LORD make you one with your wife? In body and spirit you are his. And what does he want? Godly children from your union.” (Malachi 2:15 NLT) The blessing of the multiplication of children of God has been and continues to be God's desire. Adam was given the first opportunity, and Genesis 5:4 indicates that he didn't forget God's words, and he and Eve produced an unspecified number of sons and daughters.
Genesis chapter 6 records how humanity did indeed multiply, but quickly became entirely depraved, so God had Noah build an ark for his family, and animals, to begin again. After the flood, when the land was dry enough to exit the ark, God's original idea was repeated to Noah and his sons. “Be fruitful and multiply, and fill the earth.” (Genesis 9:1) Many years later, God revealed His will to Abraham. “...blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore.” (22:17)
Again, to Abraham's son, Isaac, God repeated His plan. “I am the God of your father Abraham; do not fear, for I am with you. I will bless you and multiply your descendants for My servant Abraham's sake.” (26:24) And to Jacob, son of Isaac, God said, “I am God Almighty. Be fruitful and multiply; a nation and a company of nations shall proceed from you, and kings shall come from your body.”
The pattern is clear. God wanted Adam and Eve to multiply righteous offspring, and when the world became filled with degenerates, God began again with Noah and his family. When it was clear that only a handful of people would ever choose to love and worship the one true God, God became even more selective. Before Moses' death, he addressed the descendants of Jacob, confirming His promise, and His conditions. “ I command you today to love the Lord your God, to walk in His ways, and to keep His commandments, His statutes, and His judgments, that you may live and multiply; and the Lord your God will bless you in the land which you go to possess.” (Genesis 30:16)
God still wants more children, and He still loves multiplication. On the day of Pentecost, after Peter's sermon, many came to believe in Jesus Christ and were born into God's family. “Then those who gladly received his word were baptized; and that day about three thousand souls were added to them.”
Summing up the days that followed, it says, “And the Lord added to the church daily those who were being saved.” (2:41, 47; 5:14) As numbers of believers grew and began to infiltrate the population of Jerusalem, “believers were increasingly added to the Lord, multitudes of both men and women.” But God has never changed His mind, and still prefers multiplication. Jesus said before His ascension that He wanted the apostles to witness for Him “in Jerusalem, and in all Judea and Samaria, and to the end of the earth.” (Acts 1:8)
As believers were added and added, the adversary tried to obstruct the increase of God's people, as he has tried all along to do. After the enemy's number one man, Saul, was converted to Christianity, the doors flew open for the next level of mathematical expansion, multiplication. “Then the churches throughout all Judea, Galilee, and Samaria had peace and were edified. And walking in the fear of the Lord and in the comfort of the Holy Spirit, they were multiplied.“ (Acts 9:31) The blessing of multiplication originally given to Adam is still in effect. “Go therefore and make disciples of all the nations.“
