We don’t know the day or time of the rapture. And it’s not about the date of the rapture. It’s about our personal relationship with Jesus; it’s about our faith.
“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. 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.” (1 Thessalonians 4:16-17; NIV)
At the time of the rapture, Jesus comes into the sky, which we can see with our eyes (clouds, atmosphere) and we go up to meet Him. Jesus does not set foot on the Earth at the time of the rapture; this will happen at His second coming at the end of the seven-year tribulation.
