Summary of what i learnt;
In the beginning, it was only one language that man was known with, during the time of Adam and Eve and they where the only human that never experienced what childhood was. They learn how to speak from God because God and man communicated and man an Angels spoke together after they were created, that is to say, they heard from God and it has proven the authenticity of the bible Proving the existence of God. One of the greatest existence of man as a living being, is the power of hearing. So Adam and Eve learnt how to pronounce words from God. Without God speaking to humanity, humanity wouldn't have learn how to speak languages. The best teacher is the lord while experience is a good teacher. The Hebrews where the first people God spoke to, that's to say the first language man learnt was Hebrew language and he also gave them laws that will guide them as God's people. When a prophet speaks and it didn't come to pass, automatically you will know that the lord didn't speak. When ever the lord speaks to men, it always come to pass, for he was the one that taught them how to speak. God is still speaking and he will always speak through men that obeys his words and keep his commandments. The bible is the only book that proves itself. So keep reading the bible and get wisdom to do exploit for the lord, for surely he will speak to you as long as you are faithful to him and his word. All you need, is to be obedient to his word.
