I turn to you, brothers and sisters at home! Do you know that if God is calling you, and you refuse to obey you will hardly know how to bear what will happen afterwards? Sooner or later you will know, yea burn through every part of your being, with the knowledge that you disobeyed, and lost your chance, lost it for ever. For that is the awful part. It is rarely given to one to go back and pick up the chance he knowingly dropped. The express of one's life has shot past the points, and one cannot go back; the lines diverge. "Some of us almost shudder now to think how nearly we stayed at home," a missionary writes. "Do not, I beseech you, let this great matter drift. Do not walk in uncertainty. Do not be turned aside. You will be eternally the poorer if you do." It may be you are not clear as to what is God's will for you. You are in doubt, you are honest, but a thousand questions perplex you. Will you go to God about it, and get the answer direct? If you are puzzled about things which a straightforward missionary can explain, will you buy a copy of _Do Not Say_, and read it alone with God? Let me emphasise that word "alone." "Arise, go forth into the plain, and I will there talk with thee." "There was a Voice . . . when they stood and had let down their wings." Oh, by the thought of the Day that is coming, when the fire shall try all we are doing, and only the true shall stand, I plead for an honest facing of the question before it is too late! But this is not our strongest plea. We could pile them up, plea upon plea, and not exhaust the number which press and urge one to write. We pass them all, and go to the place where the strongest waits: God's Glory is being given to another. This is the most solemn plea, the supreme imperative call. "Not mere pity for dead souls, but a passion for the Glory of God, is what we need to hold us through to victory."
