I wrote a book called Managing Spiritual Growth. Jesus said, But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. This is the way I did it. I've been a Christian for 75 year. I also teach home bible studies. God's army as any army will get it's power and authority by rank. This is what the book is about.
