Fellow Christians: Where in the Bible does it say Jesus will return invisibly?

On the conarty it teaches that his return will be visible and personal, and this will be preceded by many signs cf Luke 21:25-28. Yoiu might be thinking of the early page in Luke where Jesus tells us not to 'Look here or look there.. '(Luke 17:22). This does not mean we will not see Jesus when he returns, but rather we are not to be lead astray by false prophets, teachers, and those claiming to be Jesus Christ.
