I read the fine print "as a group." At one the point the WTS said that some faithful jw individuals might die due to illness but not due to direct execution by God so would be resurrected.
*** w75 6/15 p. 377 par. 10 ***Should we expect, moreover, that because Jehovah is on our side he will miraculously intervene to protect each one of us personally from death or injury during the “great tribulation”? Both Psalm 91:7-12 and Proverbs 3:25, 26 have been mistakenly cited by some as supporting this view. The psalm says: “A thousand will fall at your very side and ten thousand at your right hand; to you it will not come near.” Lest we read into this text more than it states, we must ask ourselves if Moses is here talking about the coming “great tribulation” and is declaring a blanket protection for individual servants of God then. This would hardly be so when we remember that centuries later Paul showed that up to his time the devoted followers of Jehovah had undergone mockings, scourgings, prisons, tribulations and many other persecutions, even violent death. However, we can be assured that, as a group, Jehovah will protect them from being exterminated by their enemies during the “great tribulation,” and He, himself, will not touch them during his executing of adverse judgments.—Heb. 11:36-38.
*** w74 3/15 p. 172 What Protection for God’s People? ***
SURVIVAL THROUGH DIVINE PROTECTION
When the "great tribulation" destroys this ungodly system there will definitely be survivors. In fact, the Bible refers to a "great crowd" who "come out of" or survive this "great tribulation." (Rev. 7:9, 14) Jehovah God will not allow the haters of his people to vent their rage to the point of exterminating them. By means of his Son and the angelic forces, he will come to the defense of his people, rescuing them from annihilation. They being his "loyal ones," their death as a people would be too "precious," too costly, in his eyes. (Ps. 116:15) They will also be shielded from the execution of divine judgment. Neither Jesus Christ nor his angelic forces will make a mistake. None of God’s servants will be swept away along with the wicked.
Even if some do die at the hands of the enemy, their death would serve for the vindication of God’s holy name. Is your love for God of such a quality that, faced with death, you would count it a privilege to prove your loyalty to him no matter what the cost? Such a firm stand would glorify Jehovah and it would prove false Satan’s claim that your service to God is based on selfish considerations.
One thing we definitely know: Jehovah God will never allow his loyal servants to be effaced from the earth. And not a single one of them will perish at the hands of Jesus Christ or his executional forces.
