Jesus is indeed the Truth, the Way and the Life. No can ever see the Father except he has first of all known Jesus. Don't make the mistake of thinking that heaven is possible for you if you don't know the Lord Jesus. There is no other mediator, no other teacher, no other example, no other path to follow that can lead you to heaven to witness the eternal Glory of the Lord Almighty if you do not know his Only begotten Son Jesus Christ.
