God's first commission to man was to "multiply and replenish the earth".
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)
The emphasis was on people. The goal was to fill the earth with men and women created in the image of God with a personal relationship with God. But in Genesis 11:1-9 we find the emphasis was changed by man.
Go to, let us go down, and there confound their language, that they may not understand one another's speech. So the Lord scattered them abroad from thence upon the face of all the earth: and they left off to build the city. Therefore the name of it is called Babel: because the Lord did there confound the language of all the earth: and from thence did the Lord scatter them abroad upon the face of all the earth. (Genesis 11:7-9)
And Saul was consenting unto his death. And at that time there was a great persecution against the church which was at Jerusalem; and they were all scattered abroad throughout the regions of Judaea and Samaria, except the apostles. (Acts 8:1)
Therefore they that were scattered abroad went every where preaching the Word. (Acts 8:4)
Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened. (Matthew 13:33)
The parable of the net cast into the sea revealed that the Kingdom of God will draw men and women of all nations.
And he said, So is the kingdom of God, as if a man should cast seed into the ground; And should sleep, and rise night and day, and the seed should spring and grow up, he knoweth not how. (Mark 4:26-27)
Fear not, little flock; for it is your Father's good pleasure to give you the Kingdom. (Luke 12:32)
And I heard a loud voice saying in Heaven, Now is come salvation, and strength, and the Kingdom of our God, and the power of His Christ: for the accuser of our brethren is cast down, which accused them before our God day and night. (Revelation 12:10)
And the Lord shall deliver me from every evil work, and will preserve me unto his heavenly kingdom: to whom be glory for ever and ever. Amen. (II Timothy 4:18)
That ye would walk worthy of God, who hath called you unto His Kingdom and glory. (I Thessalonians 2:12)
