When man refused to hear and obey God’s Word in Genesis 10 and united to build a life without Him. God came down and confused their languages so they could not understand each other. This brought alienation between 
different peoples of the various languages and pushed them to “fill the earth” as God had directed as they moved away from each other into their own countries. Genesis 10 tells us there were 70 countries formed at that time, each with its own language that the others could not understand. It is the inability to “understand” each other, even today, that causes much alienation and bitterness in all of our relationships. But immediately following the dispersion of the nations according to their languages, God “spoke” to a man named Abraham, who heard Him and understood His call to faith. God called Abraham to trust Him and to be the father of all those who would trust Him.
But the descendants of Abraham, the Israelites, stopped listening to God and therefore they stopped trusting Him. Jeremiah brought God’s message to them in words they could understand. In Jeremiah 5:15, he said, “Behold, I am bringing against you a nation from afar, O house of Israel, declares the LORD. It is an enduring nation; it is an ancient nation, a nation whose language you do not know, nor can you understand what they say.” These people will not “understand” you. They will have no mercy on you. They will not feel compassion or care anything about you. As has always been the case, conquering armies always treat their subjects as somewhat less than themselves – less than human. When there is no common communication there is no understanding.
After Jesus death, burial and resurrection He appeared to His disciples in the upper room. After that miraculous encounter, Peter and the rest spoke to the world in everyone’s own language. The dispersion of the Nations that had begun in Genesis 11is reversed in Jesus Christ. He is God’s living Word, that can be understood by all! It’s the strongest expression of the three little words everyone loves to hear; “I love you.” Nobody explains it better than the Apostle Paul. In Romans 8:37-39 he writes, “…we are more than conquerors through him who loved us. For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.” Nobody speaks the universal language better than Jesus did.
