The reason why one's treatment of the remnant determines one's destiny is that the remnant have been anointed with Jehovah's spirit in these last days and are in line for a place on the heavenly throne with the King. Mistreatment of the remnant brings the greatest punishment, for it is an overt assault against the kingdom. Those of the sheep class know what they are doing, even though they do not see the reigning King with their literal eyes. Jehovah God's Answer - Grace Jehovah God has spoken. The basis of God's favorable judgement of anyone, including you, is contained in one word - grace.
Grace is unmerited favor.
It is favor which may not, cannot, and will not be based in any way on works of merit. You cannot pay for a free car. If you do then it is no longer free. Similarly, you cannot merit unmerited favor. If you do merit it, it is no longer unmerited.
