We are in danger of getting the barter spirit when we come to God, we want the witness before we have done what God tells us to do.  “Why does not God reveal Himself to me?”  He cannot; it is not that He will not, but He cannot, because you are in the road as long as you won’t abandon absolutely to Him.  Immediately you do, God witnesses to Himself; He cannot witness to you, but He witnesses instantly to His own nature in you.  If you had the witness before the reality, it would end in sentimental emotion.  Immediately you transact on the Redemption and stop the impertinence of debate, God gives you the witness.  As soon as you abandon reasoning and argument, God witnesses to what He has done, and you are amazed at your impertinence in having kept Him waiting.  If you are in debate as to whether God can deliver from sin, either let Him do it, or tell Him He cannot.  Do not quote this and that person, try Matthew 11:28, “Come unto Me.”  Come, if you are weary and heavy laden; ask if you know you are evil (Luke 11:13).

The simplicity that comes from our natural commonsense decisions is apt to be mistaken for the witness of the Spirit, but the Spirit witnesses only to His own nature and to the work of Redemption, never to our reason.  If we try to make Him witness to our reason, it is no wonder we are in darkness and perplexity.  Fling it all overboard, trust in God, and He will give the witness.
