Have you ever wondered if the thoughts and ideas in your head are from God?  Moroni teaches us the way to tell.  If the thought leads you to do good things and to feel good, it is from God.  If the thought makes you feel bad inside or leads you to do something unkind or not good, then it is from Satan.  God makes it very easy to tell.  

Mormon writes his son Moroni.  He tells him he has heard Moroni is wondering about baptism for little children.  Little children do not need baptism.  They are whole. God loved little children. All children will be saved. We baptize at the age of 8.  That is when God said they become accountable.  That means they can know the difference between right and wrong.  

Moroni teaches about Faith in Moroni 7.  Faith that brings miracles.  A miracle like Jesus being resurrected, or Nephi getting the Brass Plates.  

Summary Moroni, still in hiding, teaches about baptism.  He teaches about the gift of the Holy Ghost.  He teaches baptism is done at the age of accountability so that we are old enough to understand and willingly choose.  

Moroni is in hiding from the Lamanites.  He will not deny the Christ and he knows the Lamanites will destroy anyone who believes in Christ.  He teaches us about the Holy Ghost, about Priesthood ordinations, and the Sacrament.  What a blessing he added those to the Book of Mormon so we would have them in our day.
