These are the references in THE DISCOURSE to Christ's COMING:
Luk 21:27
And then shall they see the Son of man coming in a cloud with power and great glory.
Mat 24:30
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.
Mat 24:31
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.
Mar 13:26
And then shall they see the Son of man coming in the clouds with great power and glory.
13:27
And then shall he send his angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.
Nothing in the DISCOURSE about Jesus' feet hitting the earth.
Quite different from Zechariah 14 -- where His feet hit Mt of Olives and split it -- the discourse does not say that.
In fact, except for this phrase:
"and then shall all the tribes of the earth mourn"
a pretribber could have a field day with the Discourse's references and try to use it to support a "two-stage coming" and their "secret rapture"
No such thing as a pretrib Rapture, since the Rapture and Resurrection occur at His coming, along with the destruction of the antichrist, lawless one, man of sin, son of perdition or any other name the bible describes him as.
The Resurrection and Rapture as well as the destruction of the coming antichrist, occur at His coming.
So there is no case for two comings of the Lord, which is why I say if you believe Zechariah 14 and matthew 24 are not a description of the coming of the Lord with His saints, then you must believe there are two of these events in which the lord comes with His saints and destroys the wicked, on the Day of the Lord.
15 For this we say to you by the word of the Lord, that we who are alive
and remain until the coming of the Lord will by no means precede those who are asleep. 16 For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive
and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. 18 Therefore comfort one another with these words.
1 Thessalonians 4:15-18
This is describing the Day of the Lord, in which the Lord will gather His people together and destroy the antichrist and the wicked.
Zechariah 14, and Matthew 24, and 1 Thessalonians 4:15-5:4, and 2 Thessalonians 2:1-11, as well as 2 Thessalonians 1:7-10, as well as other places in which different aspects of this event are described.
so Christ was offered once to bear the sins of many. To those who eagerly wait for Him
He will appear a second time, apart from sin, for salvation. Hebrews 9:28
