JOHN: THE GOSPEL OF BELIEF - At the very least Jesus surely reminds us believing in Him isn’t merely a mental process. His life dominates only from the inside out. His presence and grace is proven in the doing of His will - John 7:17 - “If anyone’s will is to do God’s will, he will know whether the teaching is from God or whether I am speaking on my own authority.” That’s what Jesus meant by an inside-out belief in Himself.
