I believe one of the greatest tragedies of the Christian experience is that the modern-day Christian relies more on other human beings to teach them than we do the Holy Spirit.
We rely more on what we are taught through sermons, books, or teaching we receive through TV or other forms of audio media than we do on the ministry of the Holy Spirit.
He is the greatest gift that God could ever give to a human being and you need to diligently pursue developing your friendship and relationship with Him. After all, He is the spiritual life force that was in Jesus while Jesus was physically on this earth.
God never promised to give us a new book of instructions, or a new physical person to replace Jesus when Jesus was taken to heaven. Jesus promised to send us the Holy Spirit to live IN us to be our TEACHER. John 14:16,17, & 26. That, my friends, is the new covenant promise of God.
I am not saying that you should not listen to Bible teachers, but they are not the ones who actually wrote the Book.
The Holy Spirit is the Divine Enabler who enables us to live the life of a new creation in the Covenant Kingdom of the Lord Jesus.
