The Holy Spirit is bound to the truth and does not operate or reveal anything outside the truth because he is the Spirit of truth (Jn 15:26,16:15). There is no law against the fruit of the Spirit (Gal 5:23) because the fruit of the Spirit is according to truth (Eph 5:9). We don't obey the Spirit according to truth but we obey the truth according to the Spirit that guides and reveals it to us (1Pt 1:22, Jn 16:13). All truth comes from the word and there is no truth outside the word (Jn 1:14, 17:17, 2Cor 6:7, Eph 1:13, Col 1:5, 1Thes 2:13, 2Tim 2:15, Jm 1:18). The scriptures that we have been given contain all truth and the Spirit adds nothing to it and can take nothing away from it. If we add or take something away from the truth we are trying to break the truth and the truth of the scriptures can not be broken (Jn 10:35). If we say we have received something from the Spirit that adds or takes away from the word, then it is not the truth and the Spirit never gave it to us. There are others sources it came from but not from the Holy Spirit of God. There in one clear example of adding and taking away from the truth and it is located in Gen 3:3-5;

3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
4 And the serpent said unto the woman, Ye shall not surely die: (the serpent took away something bad)
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil. (the serpent added something good)

I think we know where that source came from and what is was designed to do with the first woman and man that God had created. Chew on this: 'Iniquity is the activity of rebellion that goes against the authority of truth by adding to the truth and taking away from the truth. When that has been achieved in the heart of man, then man has been beguiled away from the truth and lives in the knowledge of good and evil and calls it God'.

Every single strategy, device, word and doctrine that is expressed by the devil, comes from the iniquity that was found in him and has no truth in it no matter how much it sounds lke the scriptures. Iniquity will always try to nullify the authority of God in a situation and hinder the work of God in a local church. This is why the message that comes from God is criticized and challenged. Somebody always wants to add something to it (challenge) or take away from it (criticize). These are common place in local churches that are on fire for God and living in the will of God through the filling of the Spirit. Anytime that you hear of a ministry that is being slandered and maligned, even by its own people, you can be sure that the word is being preached in the power of the Spirit and they are taking up their cross and following Christ.
