Moses was also a stutterer and God chose him for a very important task. At first moses denied the call, because as we stutterers know, it is difficult for us to be a leader, but he truly wanted to obey God, and thats why God encourage him and didnt give up on him. But note that it doesnt say that God cured moses stutterer, rather God asked moses brother to speak for him. Of course God could have cured him. However, is not what we want or what we think is best, instead, it is what God wants and what He think is best, because nobody knows more than Him. Thats why we christians pray to God to give us strength to follow the will he has for us. The true cure is to accept God will and pray for others. But we will have our differences in religion ideology. Just remember that you will always encounter bad people and bad situations, even if you are a stutterer or not. And that first comment, he says God isnt real. Even if God cured him, he still wouldnt believe lol. People have the idea that they DESERVE to be helped, but in reality we dont deserve anything, we are all sinners. But thats another subject.
