Helaman 10
Nephi told the people “If God could give such great power to [Moses] then why not give power to me to prophesy?” How gratifying to have the Lord come and tell him afterwards that anything he says will come to pass. This power that your words will all be fulfilled and sealed because you will “ask nothing amiss” is the logical conclusion to the path of having the Lord grant whatsoever you will ask in His name which is right. Eventually you will become so familiar with what is right that you will only ask for that which the Lord will give.
