Here is a good one form that new book Bearing Thorough witness.
“Peter Was in Great Perplexity” (Acts 10:9-23a)
8 Still on the rooftop, “Peter was in great perplexity” over the meaning of the vision when messengers from Cornelius approached the house. (Acts 10:17) Would Peter, who had three times said that he would refuse to eat foods considered unclean according to the Law, be willing to go with these men and enter into the home of a Gentile? In some way holy spirit made God’s will known in this matter. Peter was told: “Look! Three men are seeking you. However, rise, go downstairs and be on your way with them, not doubting at all, because I have dispatched them.” (Acts 10:19, 20) The vision of the sheetlike vessel that Peter had received no doubt prepared him to yield to the leadings of the holy spirit.
9 Learning that Cornelius had been divinely instructed to send for him, Peter invited the Gentile messengers into the house “and entertained them.” (Acts 10:23a) The obedient apostle was already adjusting to new developments in the outworking of God’s will.
10 To this day, Jehovah leads his people progressively. (Prov. 4:18) By means of his holy spirit, he is guiding “the faithful and discreet slave” and its Governing Body. (Matt. 24:45) At times, we may receive clarifications in our understanding of God’s Word or changes in certain organizational procedures. We do well to ask ourselves: ‘How do I respond to such refinements? Do I submit to the leadings of God’s spirit in these matters?’
As brought out in other threads, doesn't the holy spirit get it right the first time? How does anyone really know they have holy spirit on their side? I guess we just have to have blind trust and never ask questions of the GB interpretation.
