Hello Danny. Thanks for your input here. When you say “ages”, I assume that you are referring to what is commonly called “dispensations”. If that is correct, then the answer is three. There have been three dispensations, of God’s dealing with mankind. The first dispensation was the “patriarchal dispensation” when God spoke His will directly to the heads of the family, or in other words, to the “patriarchs” of the family. (such as Adam, and Noah, and Abraham) The second dispensation, was the “Mosaic dispensation” when God spoke His will to the nation of Israel, through His servant Moses. The third and last dispensation, is the “Christian dispensation” in which we now live. It’s during this last dispensation, that God spoke His will to all nations, through His Son, Jesus Christ. I hope this answers your question.
