“Let not your heart be troubled; you believe in God, believe also in Me. In My Father’s house are many mansions; if it were not so, I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may be also."
If Jesus is coming to receive us and bring us to heaven to mansions He has prepared, then we know that the rapture is pre-Tribulation because after the Tribulation, we are returning with Him to help set up His Kingdom here on earth to rule and reign with Him for 1000 years! If the rapture was post-Tribulation, then Jesus would not be coming to bring us to heaven to mansions He has prepared. I hope that encourages you today!
