Jesus said that we will know the truth about Himself only if we are willing to do His will, that is, if we allow ourselves to be changed by the truths we find in Scripture. He said, 'If any man's will is to do His will (that is, if he determines to do it), he shall know whether the teaching is from God or whether I am speaking on my own authority' (John 7:17). We must not assume that we will be able fully to understand any passage of Scripture unless we are willing to be changed by it.
