Why can't Jesus periodically visit Earth? “But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only.


Matthew 24:36



The Gospel of Matthew tells us that Jesus will return someday. All Christians yearn for his return.

But why is Jesus scheduled to return only once at some indefinite time in the future?

Why can't He periodically visit Earth?

Is he "busy" visiting other planets? Does he need to do "chores" in Heaven?
John 16: 


  7 But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate will not come to you; but if I go, I will send him to you.


I have heard it said that Jesus going away physically allows for God to be spiritually with everyone.  One can imagine the "scandal" if Jesus were only to visit a few people in bodily form, once in a while. Wouldn't it be a bummer if your spouse said, "Jesus stopped by before you got home from work and gave me a big hug: I really needed it."
