2 Thessalonians 2:8

After the Rapture the lawless one will have greater freedom. He will do things that will eventually result in his being identified as the Antichrist. However the mere breath of the Lord Jesus’ mouth will slay him when Christ comes with His saints at the Second Coming (2 Thessalonians 1:10). The Lord’s "appearance" (Gr. epiphaneia) is a different and later event in His "coming" (Gr. parousia) than the "gathering" (Gr. episynagoges) event (2 Thessalonians 2:1). The first event is the Rapture, and the second is the Second Coming.
