*** w80 10/15 17   Execution of the "Great Harlot" Nears ***
2 Thus, God gives his humble servants special knowledge that others do not have. As the apostle Paul said: “This wisdom not one of the rulers of this system of things came to know . . . For it is to us God has revealed them through his spirit.” (1 Cor. 2:8-10) Having advance knowledge from Jehovah, his servants are equipped—indeed, commissioned, by God—to herald throughout the world the warning of this system’s approaching end, along with the comforting message of the new order.—Matt. 24:14.
3 Since Jehovah provides his loyal servants with advance knowledge about this system’s end, does this include information that will enable them to discern when the “great tribulation” actually has begun? Yes. What is that evidence? It has to do with God’s execution of judgment against what the Bible calls “Babylon the Great, the mother of the harlots and of the disgusting things of the earth.” (Rev. 17:5) And already, yes, right now, events are taking place that are preparing the way for that execution!

How and by what means is this special knowledge being given to the "faithful and discreet slave"?

*** w60 7/15 444  Staying Awake with the "Faithful and Discreet Slave" ***
19 Yes, the “faithful and discreet slave” was awake to the coming of 1914. In 1942 the “faithful and discreet slave” guided by Jehovah’s unerring spirit made known that the democracies would win World War II and that there would be a United Nations organization set up. Such wakefulness was concerning events that unerringly took place three years later. At the 1958 Divine Will International Assembly amazing advance information in connection with Daniel’s prophecy was given about events to occur in the immediate future. Such evidence of spiritual foresight is recorded for us in the book “Your Will Be Done on Earth.” Onceagain the “faithful and discreet slave” has been tipped off ahead of time for the guidance of all lovers of God. Surely one’s present security depends on his staying awake with the “faithful and discreet slave.”

How was the “faithful and discreet slave” tipped off ahead of time by knowing the democracies would win World War II  along with a United Nations organization set up?

7 Let us now unmistakably identify Jehovah’s channel of communication for our day, that we may continue in his favor. Listen to the inspired answer to the situation, in Matthew 24:45-47 (NW): “Who really is the faithful and discreet slave whom his master appointed over his domestics to give them their food at the proper time? Happy is that slave if his master on arriving finds him doing so. Truly I say to you, He will appoint him over all his belongings.” And has he? Yes, particularly since 1919 has it been true that he has appointed the collective body of the anointed remnant over all the visible interests of the Kingdom. The “slave” then became responsible not only for ministering to the needs of the anointed body members but also for taking on the responsibility of preaching the good news of the established Kingdom to people of all nations. (Matt. 24:14) Such is true not by their determination of it, but because God himself has so directed. “God has set the members in the body, each one of them, just as he pleased,” is the way it is pictured in 1 Corinthians 12:18 (NW). It is vital that we appreciate this fact and respond to the directions of the “slave” as we would to the voice of God, because it is His provision.

How does the Watchtower Society know that Jehovah chose it as "THE ONLY TRUE RELIGION" in 1919? Has the Society shown itself to be "faithful and discreet" by making false predictions regarding the time of the end? Can the Society rightly insist that true Christians place full trust and confidence in its words, predictions and claims, when many have changed over the years? How can we respond to the directions of the "slave" as we would the voice of God when their directions are false predictions of false dates?

God’s spirit operates upon his dedicated servants today, not to inspire them, but to move them gently in the direction of increased understanding. It permits them to make mistakes as they grow in understanding of God’s Word, but in time it helps them to see their mistakes, which they gladly correct.

How does God's spirit move them gently, but not inspire them? The word inspire or inspiration means:  Something conveyed to the mind;  to communicate divine instruction;  to infuse ideas.
