The Tower of Babel is the story of man’s self-reliance vs reliance on God. It points us toward Pentecost and the birth of the Church.
Then they said, "Come, let us build ourselves a city, and a tower with its top in the heavens, and let us make a name for ourselves, lest we be scattered abroad upon the face of the whole earth." (Genesis 11:4)
Mankind tries to reach heaven by his own ingenuity - bricks and bitumen to build a tower with its “top in heaven.” They build themselves a city. It’s about self reliance instead of reliance on God.
Notice also that they try to make a name for themselves. The person who names you in the Bible is the person you serve and the person from whom you get your identity and purpose. God names Adam. Adam names the beasts. God renames Abram to Abraham. Jesus names Peter. The people of Babel try to make a name for themselves - they serve themselves and get their identity from their own accomplishments. The result is that God confuses their language and scatters the people.
***Come, let us go down, and there confuse their language, that they may not understand one another’s speech." So the LORD scattered them abroad from there over the face of all the earth, and they left off building the city. *(Genesis 11:7-8)
Contrast the scattering of the people in Babel with the birth of the Church at Pentecost.
When the day of Pentecost had come, they were all together in one place. (Acts 2:1)
The birth of the Church reunites man “in one place”, reversing the scattering of the people at Babel. The message of the Gospel reunites man under one common language, the language of forgiveness and love, and they all understand each other again.
And how is it that we hear, each of us in his own native language? (Acts 3:8)
Pentecost reverses the tower of Babel, reunites man under the common language of the Gospel and reorients man to serve and get his purpose from God. Pentecost also reverses the sin at Mt. Sinai when Israel worshiped the golden calf.
*And the sons of Levi did according to the word of Moses; and there fell of the people that day about three thousand men. (Exodus 32:28)
So those who received his word were baptized, and there were added that day about three thousand souls. (Acts 2:41)*
3000 were lost at Mt. Sinai. 3000 were baptized and saved at Pentecost.
Pentecost is a complete reversal of both Babel and Mt. Sinai.
