Mark 13:24-27 — the visible, unmistakable return of Christ after the tribulation

After the tribulation: the sun darkened, moon gives no light, stars fall from heaven, powers of heaven shaken. Then 'they will see the Son of Man coming in the clouds with great power and glory' and angels gather the elect from the four winds. Mike links to Revelation 1:7 — 'every eye will see him, even those who pierced him.' The point: the second coming will be globally visible and unmistakable. This is why any 'private' return (JW doctrine) or invisible coming is ruled out. Also rules out preterist readings that treat AD 70 as a form of Christ's coming.
