        Every Christian is called to make known to others the unsearchable
      
      
        riches of Christ; therefore he should seek for perfection in speech.
      
      
        He should present the word of God in a way that will commend it
      
      
        to the hearers. God does not design that His human channels shall
      
      
        be uncouth. It is not His will that man shall belittle or degrade the
      
      
        heavenly current that flows through him to the world.—

        They will be educated in patience, kindness, affability, and help-
      
      
        fulness. They will practice true Christian courtesy, bearing in mind
      
      
        that Christ, their companion, cannot approve of harsh, unkind words
      
      
        or feelings. Their words will be purified. The power of speech will
      
      
        be regarded as a precious talent, lent them to do a high and holy
      
      
        work.—

        Mental Culture
      
      
        Mental culture is what we, as a people, need and what we must
      
      
        have in order to meet the demands of the time.—

        .
      
      
        We must not enter into the Lord’s work haphazard, and expect
      
      
        success. The Lord needs men of mind, men of thought. Jesus calls
      
      
        for coworkers, not blunderers. God wants right-thinking and intelli-
      
      
        gent men to do the great work necessary to the salvation of souls.—

        Some need to discipline the mind by exercise. They should force
      
      
        it to think. While they depend upon some one to think for them, to
      
      
        solve their difficulties, and they refuse to tax the mind with thought,
      
      
        the inability to remember, to look ahead and discriminate, will con-
      
      
        tinue. Efforts must be made by every individual to educate the mind.—

        God does not want us to be content with lazy, undisciplined minds,
      
      
        dull thoughts, and loose memories.—
