and they will see the Son of man coming on the clouds of heaven with power and great glory.”​—Matt. 24:30.

When he comes “with the clouds, and every eye will see him” he will be invisible to fleshly eyes. (Rev. 1:7) “Clouds” would naturally hide anyone in them, the expression therefore symbolizing that the one “coming” is himself invisible. Not with fleshly eyes in a literal sense, but from observation of what the Son of man does at that time, everyone will see that what takes place is not from men, but from heaven.
