How is he twisting what pretrib/premil teaches?
Pretrib/Premil teaches that the following two passages refer to two different events.
1 Thess 4:14 For we believe that Jesus died and rose again, and so we believe that God will bring with Jesus those who have fallen asleep in him. 15 According to the Lord’s word, we tell you that we who are still alive, who are left until
the coming of the Lord, will certainly not precede those who have fallen asleep. 16 For
the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17 After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.
Matthew 24:29 “Immediately after the distress of those days “‘the sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken.’ 30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will mourn
when they see the Son of Man coming on the clouds of heaven, with power and great glory. 31 And he will send his angels with a loud trumpet call, and they will gather his elect from the four winds, from one end of the heavens to the other.
Both of these passages refer to the coming of Christ. But pretrib/premil sees them as being separate events. So, how can you deny that pretrib/premil teaches a second (1 Thess 4:14-17) and third (Matt 24:29-31) coming of Christ?
