Confused?

Genesis 11:5-9 (ESV Strong's)

5 And the Lord came down to see the city and the tower, which the children of man had built. 6 And the Lord said, “Behold, they are one people, and they have all one language, and this is only the beginning of what they will do. And nothing that they propose to do will now be impossible for them. 7 Come, let us go down and there confuse their language, so that they may not understand one another's speech.” 8 So the Lord dispersed them from there over the face of all the earth, and they left off building the city. 9 Therefore its name was called Babel, because there the Lord confused the language of all the earth. And from there the Lord dispersed them over the face of all the earth.

Adam was removed from the Garden before he could eat from the tree of life because of his disobedience to the Lord. The Lord confused the language of the children of man and dispersed them before they could attempt to reach heaven on their own. It is the nature of man to seek a name for himself rather than the name of the Lord. This is what makes the forbidden fruit so attractive. 

At Pentecost, the Holy Spirit would bring order to this confusion of language. The Lord would provide the way into heaven. The one place this is possible is at the feet of Jesus Christ. It is when we confess the word of the Lord that the kingdom of heaven is opened to us. This is why He comes to us. 

Acts 2:1-4 (ESV Strong's)

The Coming of the Holy Spirit

1 When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
