You must all have heard the name of a book that has helped many a saint now in glory to the examination and the keeping of his own heart.  I refer to Jeremy Taylor’s Holy Living and Dying.  Take two or three of Taylor’s excellent rules with you as you go down from God’s house to-night.  ‘If you would really live a holy life and die a holy death,’ says Taylor, ’learn to reflect in your every action on your secret end in it; consider with yourself why you do it, and what you propound to yourself for your reward.  Pray importunately that all your purposes and all your motives may be sanctified.  Renew and rekindle your purest purposes by such ejaculations as these:  “Not unto us, O God, not unto us, but to Thy name be all the praise.  I am in this Thy servant; let all the gain be Thine.”  In great and eminent actions let there be a special and peculiar act of resignation or oblation made to God; and in smaller and more frequent actions fail not to secure a pious habitual intention.’  And so on.  And above all, I will add, labour and pray till you feel in your heart that you love God with a supreme and an ever-growing love.  And, far as that may be above you as yet, impress your heart with the assurance that such a love is possible to you also, and that you can never be safe or happy till you attain to that love.  Other men once as far from the supreme love of God as you are have afterwards attained to it; and so will you if you continue to set it before yourself.  Think often on God; read the best books about God; call continually upon God; hold an intimate communion with God, till you feel that you also actually and certainly love God.  And though you begin with loving God because He first loved you, you will, beginning with that, rise far above that till you come to love Him for what He is in Himself as well as for what He has done for you.  ‘I have done this in order to have a seat in the Academy,’ said a young man, handing the solution of a problem to an old philosopher.  ‘Sir,’ was the reply, ’with such dispositions you will never earn a seat there.  Science must be loved for its own sake, and not for any advantage to be derived from it.’  And much more is that true of the highest of all the sciences, the knowledge and the love of God.  Love Him, then, till you arrive at loving Him for Himself, and then you shall be for ever delivered from all self-love and by-ends, and shall both glorify and enjoy God for ever.  As all they now do who engaged their hearts on earth to the service and the love and the enjoyment of God is such psalms and prayers as these:  ’Whom have I in heaven but Thee? and there is no one on earth that I desire beside Thee.  How excellent is Thy loving-kindness, O God!  The children of men shall put their trust under the shadow of Thy wings.  For with Thee is the fountain of life, and in Thy light shall we see light.  As for me, I will behold Thy face in righteousness:  I shall be satisfied when I awake with Thy likeness.  Thou wilt show me the path of life; in Thy presence is fullness of joy, and at Thy right hand there are pleasures for evermore.’
