JWs teach that Jesus has already returned invisibly to earth in 1914.
Has Jesus return invisibly to earth?
The Bible teaches that when Jesus returns to earth, every eye will see him. Therefore, he could not have returned invisibly.
Rev 1:7 Look! He is coming with the clouds, and every eye will see him, and those who pierced him; and all the tribes of the earth will beat themselves in grief because of him. Yes, Amen.
The angels told the disciples that Jesus will come back to earth the same way he went to heaven. As the disciples saw Jesus being lifted by the cloud into heaven, when Jesus comes back again, we will see him descend upon a cloud onto earth.
9 After he had said these things, while they were looking on, he was lifted up and a cloud caught him up from their sight. 10 And as they were gazing into the sky while he was on his way, suddenly two men in white garments stood beside them 11 and said: “Men of Galʹi·lee, why do you stand looking into the sky? This Jesus who was taken up from you into the sky will come in the same manner as you have seen him going into the sky.”
Matt 24:30 Then the sign of the Son of man will appear in heaven, and all the tribes of the earth will beat themselves in grief, and they will see the Son of man coming on the clouds of heaven with power and great glory.
