The Watchtower Society provides to the Jehovah's Witnesses the service to guide them in recognizing the deep things of Jehovah. Again and again we find the term "recognize / explore the deep things of Jehovah" in different formulation in the publications of the worldwide Watchtower publishing. This is a hobbyhorse of Jehovah's organization, marketing the secrets of a certain Jehovah.
The phrase "Recognize the deep things" actually appears in the Bible. The Watchtower Society is relying on the authority of the Bible and claims to be the only institution in the world to understand the Bible correctly.

This doctrine Jesus talks about here, is the doctrine of a self-styled prophetess named Isevel (Jezebel), which was tolerated in the church at Thyatira. This single passage in the Bible that speaks of the deep things, refers to heresy and false doctrine. It is the study of the deep things of the adversary.
How do you handle it if your spiritual authority tells you things that serve lie in the front and in the back?
Take it easy one time to note that you are right on the nose guided to destruction! In the verse cited here prior to the passage we read it, that Jesus is the one who researches the hearts. This is another indication that he is the Almighty!
Will you not finally open your eyes?
Don't you want some time to note that the doctrine of Jehovah is only a big lie?
