they can ruin the influence of the holy spirit
There is only one way to be influenced by the Holy Spirit. Either one is in the flesh or in the spirit.
Romans 8: 5 For those who are in accord with the flesh set their minds on the things of the flesh, but those in accord with the spirit on the things of the spirit. 6 For the minding of the flesh means death, but the minding of the spirit means life and peace; 7 because the minding of the flesh means enmity with God, for it is not under subjection to the law of God, nor, in fact, can it be. 8 So those who are in harmony with the flesh cannot please God.
9 However, YOU are in harmony, not with the flesh, but with the spirit, if God’s spirit truly dwells in YOU . But if anyone does not have Christ’s spirit, this one does not belong to him. 10 But if Christ is in union with YOU , the body indeed is dead on account of sin, but the spirit is life on account of righteousness. 11 If, now, the spirit of him that raised up Jesus from the dead dwells in YOU , he that raised up Christ Jesus from the dead will also make YOUR mortal bodies alive through his spirit that resides in YOU .
12 So, then, brothers, we are under obligation, not to the flesh to live in accord with the flesh; 13 for if YOU live in accord with the flesh YOU are sure to die; but if YOU put the practices of the body to death by the spirit, YOU will live. 14 For all who are led by God’s spirit, these are God’s sons. 15 For YOU did not receive a spirit of slavery causing fear again, but YOU received a spirit of adoption as sons, by which spirit we cry out: “Abba, Father!”16 The spirit itself bears witness with our spirit that we are God’s children. 17 If, then, we are children, we are also heirs: heirs indeed of God, but joint heirs with Christ, provided we suffer together that we may also be glorified together.
So all of those members of the JW Great Crowd... are already not influenced by the Holy Spirit at all.
