Genesis 11:9 Therefore is the name of it 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.
Man was trying to make a name for himself. He really wanted to prove that he could live and make something of himself without God. They got together and began to build a large tower that would reach into heaven. There is a lot we do not understand about the tower but we do understand that man was together capable of anything that he sat his mind to.
God came down and confused the language so that they couldn’t talk to each other. Men began to spread out with others that could be understood.
Our goal in life should be to know God and to serve Him. Our goal in life is often to prove that we do not need God and can we can make something meaningful of ourselves on our own.
Remember who is in charge. Remember who gave you the ability to speak. Use your abilities for Him!
