May not the inadequacy of much of our spiritual experience be traced back to our habit of skipping through the corridors of the Kingdom like children through the market place, chattering about everything, but pausing to learn the true value of nothing? In my creature impatience I am often caused to wish that there were some way to bring modern Christians into a deeper spiritual life painlessly by short easy lessons; but such wishes are vain. No short cut exists. God has not bowed to our nervous haste nor embraced the methods of our machine age. It is well that we accept the hard truth now: the man who would know God must give time to Him. He must count no time wasted which is spent in the cultivation of His acquaintance.
