Following the flood, Noah's descendants failed to spread out and fill the earth as God had spoken. Rather, they exalted themselves; with "one language and the same words" (Genesis 11:1) they spoke proudly and arrogantly. The Lord humbled them by confusing "the language of all the earth," dividing and dispersing the people (Genesis 11:9). That dispersal was reversed on Pentecost Day (the fiftieth day of Easter), when God caused the one Gospel of the Lord Jesus Christ to be preached in a multitude of languages. "At thissound the multitude came together" (Acts 2:6), for the preaching of Christ is the primary work of the Holy Spirit, whereby He gathers people from all nations into one Church. The Holy Spirit teaches and brings to our remembrance the words of Jesus, which are the words of the Father who sent Him. These words bestow forgiveness and peace to those who keep and hold on to them in love for Jesus. "Peace I leave with you; my peace I giveto you. Not as the world gives do I give you. Let not your hearts be troubled, neither let them be afraid."
