One other thing, if the resurrected Jesus had stayed on the Earth to minister for awhile longer....Satan would have taken another run at him again “in attempt to consume him” perhaps with much more dire consequences...not for the Christ but for the Earth and its peoples. The Spirit had to come, Christ had to go back,,,the Father snatched him, caught him up...how ever you wish to frame it via your own favored bible versions. Indeed, it makes for a much stronger argument that it is the Holy Spirit that acts as “the Restrainer” that keeps the “son of perdition” and his “beast system” from coming into full operation until such time God is ready to do a “red sea” type destruction of evil off the face of the Earth!
The Body pf Christ is the restrainer due to the Holy Spirit in each believer.
