What humanity wrecks, God restores is a powerful look into the corrupted heart of humankind compared to the power of restoration from God.  In Genesis 11 we see the people of the world repeating the same mistake as Adam and Eve in Genesis 3, they want to be like God.  To accomplish this the people, build a tower but their quest for joy and security apart from God has disastrous consequences.  True joy and security are only found in Jesus Christ.  Good news, what humanity wrecks, God restores.
