If I am going to accept anyone's word and teaching about the Rapture it's going to be Christ teachings. Christ did teach about the Rapture in Matthew 24 and the specific reference to the Rapture comes in Matthew 24:31 and the Cosmic signs that will be in the sky are referenced both in Matthew 24 and Revelation 6. The Rapture is one thing that so many people have been taught about and yet know so little about it.
In fact so may put so much faith in a pre-trib rapture that is totally not supported by scripture and cannot even be addressed unless scripture is taken symbolically or figuratively, anything but literal. There is only ONE Rapture timing position that is backed up by literal scripture interpretation and that was taught by Christ and that is what is known as the Pre-Wrath Rapture. Not Pre-Tribulation, Not Mid-Tribulation and not Post-Tribulation but a Rapture that scripturally occurs just prior to God's Wrath being released upon the world.
Sorry to say the signs are not yet there to signal that the period or season of the Rapture is approaching and near. The first sign that will be presented unto the Church and body of Christian believers is when the Antichrist signs a 7-year peace treaty/ agreement/treaty with Israel that gives Israel the ability to restore their temple worship again. 3 1/2 years into that agreement the Antichrist will revoke that agreement and set up the abomination that causes desolation to the Israel Temple and then will also set out to destroy, kill, eliminate all Jews and Christians that will not or do not convert to Islam. I say Islam because most all the signs and information relating to the antichrist mirror the description of the Islamic Mahdi (12th Imam) that is to come in the last days along with the return of the Islamic Jesus. I'm sure these people have good intentions and really do believe in what they are saying but I can't help but believe they are not reading the truth in the Scriptures but rather are making the same errors that the pre-tribulation advocates are making and make and that is making scripture change to reflect their opinion or support their particular opinion/belief rather than taking scripture literally and taking Christ words for what He actually said.
Believers should pay attention to Matthew 24 and just what that Chapter is about and why it was written. Christ was directly and specifically ask about the END days and how to recognize them and authenticate them. Christ did answer those questions and if there is/was a pre-trib Rapture or any Rapture of the Church then it should be (and is) found there in Matthew 24.
