Hi Mark F
Because this was asked in a Pre Trib Only forum, I was under the impression that you were asking the few PreTribbers for their answer. But it looks like you have a roundhouse answer.
From my perspective, since I am a firm believer that it is God's timetable that we are on, (and not Satan's timetable or man's timetable), it is my firm belief that God, in the person of the Holy Spirit, is the only One who has the capability of restraining the inherent evil couched in the hearts of unregenerate men who are ultimately the servants of Satan.
I understand, by this, the wonderful power that the New Testament Church plays in all this. The Holy Spirit resides in us, therefore we are the hands and feet of Jesus in our world today. What this means to me is that we are "salt and light" or "preservation and flavor, as well as illumination" in a dark (evil) and dying world.
Mat 5:13 Ye are the salt of the earth: but if the salt have lost his savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
Mat 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
Joh 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
Part of the job of the Holy Spirit is threefold. He will “convict” the world of sin. He will convict the world of God's righteousness. He will convict the world of the coming judgment.
Joh 16:7 But in fact, it is best for you that I go away, because if I don't, the Advocate won't come. If I do go away, then I will send Him to you.
Joh 16:8 And when He comes, He will convict the world of its sin, and of God's righteousness, and of the coming judgment.
Joh 16:9 The world's sin is that it refuses to believe in Me.
Joh 16:10 Righteousness is available because I go to the Father, and you will see Me no more.
Joh 16:11 Judgment will come because the ruler of this world has already been judged.
Joh 16:12 "There is so much more I want to tell you, but you can't bear it now.
Joh 16:13 When the Spirit of truth comes, He will guide you into all truth. He will not speak on His own but will tell you what He has heard. He will tell you about the future.
Joh 16:14 He will bring Me glory by telling you whatever He receives from Me.
Joh 16:15 All that belongs to the Father is Mine; this is why I said, 'The Spirit will tell you whatever He receives from Me.'
How does the Holy Spirit convict (admonish against, rebuke, reprove) the world of its sin, of God’s righteousness, and of the coming judgement? He does so by the Word of God and by the contrast of good versus evil. That is where the Church comes into play. It provides the contrast.
In our world today, Spirit controlled individuals are the only ones who have any hope of overcoming a sinful nature. As long as there are Spirit controlled men and women present in our world, there will be a contrast of good vs evil.
As such, I do not see the Church as the restrainer, but rather an outworking of the power of Christ which provides a graphic demonstration of the power of the Holy Spirit, who I believe to be the restrainer.
Just observing.
