One of the key points in the teaching that Jesus will rapture His Church before the last 7 year period, known as "Daniel's 70th week" (Dan 9:24-27), is that the Holy Spirit, who resides in believers, is the "Restrainer" mentioned by Paul in (2 Thess 2:7). This has been taken as a "proof text" to fit in with their theory of a "secret rapture". The Holy Spirit is defined by Jesus, as fulfilling different roles in the life of believers when He comes, but restrainer is not one of them! Check it out for yourself in chapters 14, 15, and 16 of the Gospel of John, where the words of Jesus are recorded. Depending on which translation you use, you will find words such as, Advocate, Comforter, Counselor, Helper, Intercessor, Strengthener,----but not Restrainer. This role for Him has been added to scripture by those who are trying to prove that the Church will not go through the time of "great tribulation" at the hands of the Antichrist, during the last half of this 7 year period. Various scriptures clearly teach this, including the words of Jesus, Paul, and John, and yet these people invent a theory that attempts to prove their false teaching!
There is only one person mentioned in scripture, that I am aware of, who could fill this role of restraining evil until the time set by God to let the Antichrist start his persecution of Israel and the Church. That person is the archangel "Michael", who has been given the specific task of protecting God's people, as mentioned many times in scripture. The most important reference, relating to the subject at hand, would have to be (Dan 12:1), where he is confirmed as the one who protects the nation of Israel. At the middle of this 7 year period, we are told he will "arise", and then the Antichrist will begin his reign of terror against the people of God (Rev 13:5-10). The word here translated arise, or stand up, in most English translations could be translated as "stand still", since it is the same root word that is used to describe the miracle of the sun and the moon stopping, or standing still, so that Joshua and his warriors could complete the battle against their enemy. (Josh 10:13) By letting scripture explain scripture, we can often prevent being led into error by those who are trying to prove some theory. Let's keep in mind that God must allow His Church to be purified, and changed from their present condition, before they are ready to be raptured! This purification can only come about through a time of persecution, such as much of the Church are already experiencing in other parts of the world! Why should God exempt the church in our Western world, and keep us from this time of persecution, that He has planned to make us ready to be raptured? That doesn't make any sense to me!
