Date setting is dangerous at best. I dont see all of the prophecy fulfilled that has to precede the rapture. The only set time for the rapture is that it will happen before the peace treaty is signed with Israel. The last seven years of Daniels prophesy of 490 years for the nation of Israel starts at the signing of that peace treaty. I believe the prophecy of Ezekiel 38-39 will happen before that peace treaty is signed. Nonetheless it could happen any day prior to that war.
Where do you find this clearly in scripture, rather than on someones chart? And a peace treaty? This is a covenant that is confirmed (Daniel 9:27), which refers to the crucifixion, hence the ending of sacrifice.
I would contest that there are multiple places that indicate the timing of the rapture, and plainly:
John 6:39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
2 Thess 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
1 Cor 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
Matt 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 30
And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Revelation mentions "7" numerous times, but NEVER in terms of years. The tribulation is only 42 months or 1260 days.
Study the scriptures, not charts.
