124. The fact that wisdom, intelligence, reason, and knowledge are not man's but the Lord's is quite clear from what the Lord Himself taught, for example in Matthew, when the Lord compares Himself to a householder who planted a vineyard, and set a hedge around it, and let it out to tenants, Matt 21:33. In John,
The Spirit of truth will guide you into all the truth, for He will not speak on His own authority, but whatever He hears He will speak. He will glorify Me, for He will receive from what is Mine and declare it to you. John 16:13, 14.
Also in the same gospel,
Man cannot receive anything unless it is given him from heaven. John 3:27.
Anyone who has been granted knowledge of merely a few of heaven's arcana knows that this is true.
