Luke 24:39; "See My hands and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have."
Acts 1:10; And as they were gazing intently into the sky while He was going, behold, two men in white clothing stood beside them.
Acts 1:11; They also said, "Men of Galilee, why do you stand looking into the sky? This Jesus, who has been taken up from you into heaven, will come back in just the same way as you have watched Him go into heaven."
When Jesus comes back, it will be in a physical body. It definitely will not be a spiritual/internal thing only.
Matt 24:26; "So if they say to you, 'Behold, He is in the wilderness,' do not go out, or, 'Behold, He is in the inner rooms,' do not believe them. ( Luke 17:23; )
Matt 24:27; "For just as the lightning comes from the east and flashes even to the west, so will the coming of the Son of Man be. ( Luke 17:24; )
If someone tells you, they've had some secret, clandestine, meeting with Jesus don't believe them.
When Jesus returns, the whole world will know it.
That's not to say, we can't have a personal relationship with Jesus in our hearts, ( through the Holy Spirit )
But that isn't the second coming of Jesus.
John 16:7; "But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you.
John 14:2; "In My Father's house are many dwelling places; if it were not so, I would have told you; for I go to prepare a place for you.
John 14:3; "If I go and prepare a place for you, I will come again and receive you to Myself, that where I am, there you may be also.
John 14:4; "And you know the way where I am going."
