What I have said, however important it may be to know, does not cover the entire ground comprehended in the text.  I must show you another element which must exist in the manner of all right hearing.  That element is discrimination.  Without this, how is the hearer to know whether the truth or its opposite is being preached?  The comparison may lack adaptability in some of its points, but I have heard it said that some hearers are like young birds in their nest, ready to swallow down anything put into their mouths.  Such as hear in this way lack discrimination; that is, they do not discern the difference between what is true and what is false.  This is particularly the case with such as have been trained to regard what their own denominational ministers preach as being the truth, the whole truth, and nothing but the truth.  I am aware that some may just now be saying in their minds:  “You Dunkard people are the very ones to whom your words most justly apply; for I know of no people who take so great pains to instil this very belief into the minds of the young as you do.”  I can truthfully say that such charges are not strange to me.  But with all due respect for such as differ from us in religious faith and practice, I do say that we, as a denomination of Christian brethren, acknowledging no teacher but Christ, no authority but his Word, have no will, wish or desire to lead the truth and thus pervert, ignore or misapply any part of it; but our will, wish and desire is to be led by the truth.  And I do not in my heart believe there is one member of our Brotherhood who would desire to instill into the mind of his or her child any belief or practice not sustained by a plain “thus saith the Lord.”  In this very way the power of discrimination is developed in the minds of our young people, so that when they hear or read they do not question whether this or that that they hear or read has for its authority the Methodist Discipline, the Episcopal Prayer Book, or Lutheran Catechism; but they at once perceive that it either has or has not the sanction of God’s Word.  We are taught that in a spiritual sense no one is to be called rabbi.  “Be not ye called rabbi; for One is your teacher, and all ye are brethren.  And call no man your father on the earth; for one is your Father in heaven.”  How the mind might expatiate here in making historic disclosures of the times and ways in which this plain command of our Lord has been violated!  Hearing the Word preached, and the hearer not able to discern truth from falsehood, has given to priestcraft nearly all of its power; because priestcraft, unsupported by the common people, could never have risen into power.  If the common people had been wise enough to take heed how they hear, they never would have suffered themselves to be imposed upon as they have been.
