There is a fine devotional book which has been assembled from the writings of Dr. J. I. Packer. In it he quotes a psychologist on the six marks of maturity. Americans love to take self-examinations, so here is one for you on what it means to be grown up, to be whole, balanced, sane and able to cope with life:
    1. The first mark of maturity is the ability to deal constructively
        with reality, to face facts, to not cover up reality or call it
        something else, but to deal with it as it is.  Mature people do
        not kid themselves.
    2. The second mark is, adapting quickly to change.  We all experience
        change, whether it be physical, at work, in the family, or
        whatever.  I am amazed at how much some of you have changed
        through the years while I remain exactly the same!  Immature
        people resist change.  It makes them nervous.  But the mark of
        maturity is to adapt to change because change is inevitable.
    3. The third mark is freedom from the symptoms of tension and
        anxiety.  The worried look, the frown, the ulcers, the palpi-
        tations of the heart — all come because you are upset, anxious
        and worried.  Maturing means you have begun to see that God is in
        control of this world.  He is working out purposes that you do
        not always understand, but you accept it.  He will take you
        through the deep water, not drown you in it.  Maturity means you
        are learning to trust.
    4. Fourth, it means to be satisfied more with giving than receiving.
        Some of you have recently learned that the joy of Christmas is
        not getting presents but giving them.  To see the joy in someone
        else’s face when they get something they either need or want.
        That is a sign you are growing up.  You are discovering the true
        values of life.
    5. The fifth mark is, to relate to others with consistency, help-
        fulness and mutual satisfaction.  Maturity is learning to get
        along with other people, to be a help, not a hindrance, to
        contribute to the solution and not to be always a part of the
        problem.
    6. Finally, maturity is sublimating and redirecting anger to
        constructive ends.  Maturity is the ability to use the adrenaline
        that anger creates, not to lose your temper and add to the
        problem, but to correct a situation or to contribute to changing
        the nature of the difficulty.
