Tell me what the whole point would be if believers together were in a disorderly fashion falling upon the floor, no preaching of THE TRUTH of The GOSPEL, no outward glorifying GOD with words for HIS GRACE AND MERCY most visibly seen in HIS SON?
If an unbeliever comes in and witnesses this?
Are they led to believe?
Or rather the opposite?
I agree with you that this type of service is harmful to unbelievers. However, there is no reason to think that an orderly demonstration of the gifts of the spirit during worship and a good sermon are mutually exclusive. As Lauren has pointed out repeatedly in her posts that there is supposed to be order and not chaos. People do often twist or pervert spiritual gifts as she said. Just like there are true and false conversions there are true and false demonstrations of spiritual gifts. We don't throw out the idea of conversion because of the fake converts.
If you think about it what is more convicting and awe inspiring for an unbeliever to witness than a true demonstration of the Holy Spirit? Also, it makes sense to me that if Christians are truly being led by the Holy Spirit ( including the minister), that the minister would have a message of truth to share with his congregation. As for falling down, I would imagine there have been genuine and non genuine incidents. I don't think it's that far fetched to imagine a person being overcome by the sense of majesty and holiness of God and falling to their knees. The Holy Spirit is powerful. As Christians we are often overcome when in the presence of God. Not to mention there have been countless recorded stories of revivals ( the great awakening comes to mind) in which many in attendance during those meetings were prostrate under conviction of sins and later found salvation. (Those weren't Pentecostal or charismatic meetings). Those prostrate weren't manufacturing that.
I do agree that at times these things seem manufactured. I don't flow with everything I've ever witnessed. You have to assess each situation independently and use discernment. Simply writing off speaking in tongues as being disorderly because you don't understand the tongues isn't right.
