"And when he heard this . . ." Have you ever heard the Master say a hard word? If you have not, I question whether you have heard Him say anything. Jesus Christ says a great deal that we listen to, but do not hear; when we do hear, His words are amazingly hard.
When I have sadly misunderstood Him? (John 10:17.) It is possible to know all about doctrine and yet not know Jesus. The soul is in danger when knowledge of doctrine outsteps intimate touch with Jesus. Why was Mary weeping? Doctrine was no more to Mary than the grass under her feet. Any Pharisee could have made a fool of Mary doctrinally, but one thing they could not ridicule out of her was the fact that Jesus had cast seven demons out of her; yet His blessings were nothing in comparison to Himself. Mary "saw Jesus standing and knew not that it was Jesus . . ;" immediately she heard the voice, she knew she had a past history with the One who spoke. "Master!"
The answer to the question "How can a man be born when he is old?" is – When he is old enough to die – to die right out to his "rag rights," to his virtues, to his religion, to everything, and to receive into himself the life which never was there before. The new life manifests itself in conscious repentance and unconscious holiness.
It is very easy to quench the Spirit; we do it by despising the chastening of the Lord, by fainting when we are rebuked by Him. If we have only a shallow experience of sanctification, we mistake the shadow for the reality, and when the Spirit of God begins to check, we say – oh, that must be the devil.
The voice of the Spirit is as gentle as a zephyr, so gentle that unless you are living in perfect communion with God, you never hear it. The checks of the Spirit come in the most extraordinarily gentle ways, and if you are not sensitive enough to detect His voice you will quench it, and your personal spiritual life will be impaired. His checks always come as a still small voice, so small that no one but the saint notices them.
