The Song of [Solomon] expresses the desire implanted in every human heart, to be reunited with God Himself, and to know perfect and unbroken union with Him. He has made us for Himself, and our hearts can never know rest and perfect satisfaction until they find it in Him.
It is God's will that some of His children should learn this deep union with Himself through the perfect flowering of natural human love in marriage. For others it is equally His will that the same perfect union should be learned through the experience of learning to lay down completely this natural and instinctive desire for marriage and parenthood, and accept the circumstances of life which deny them this experience. This instinct for love, so firmly implanted in the human heart, is the supreme way by which we learn to desire and love God Himself above all else.
But the High Places of victory and union with Christ cannot be reached by any mental reckoning of self to be dead to sin, or by seeking to devise some way or discipline by which the will can be crucified.
The only way is by learning to accept, day by day, the actual conditions and tests permitted by God, by a continually repeated laying down of our own will and acceptance of His as it is presented to us in the form of the people with whom we have to live and work, and in the things which happen to us.
Every acceptance of His will becomes an altar of sacrifice, and every such surrender and abandonment of ourselves to His will is a means of furthering us on the way to the High Places to which He desires to bring every child of His while they are still living on earth.
