If someone denies the rapture event, then they need to be consistent and deny that Jesus was taken up into the sky. You cannot affirm the Ascension, while denying the rapture.
“Then we who are alive, who are left, will be suddenly caught up together with them in the clouds to meet the Lord in the air. And so we will always be with the Lord.” (1 Thess 4:17 NET)
“After he had said this, while they were watching, he was lifted up and a cloud hid him from their sight. As they were still staring into the sky while he was going, suddenly two men in white clothing stood near them and said, “Men of Galilee, why do you stand here looking up into the sky? This same Jesus who has been taken up from you into heaven will come back in the same way you saw him go into heaven.” (Acts 1:9–11 NET)
