The real presence of the LORD does not pop-up unannounced when Jesus institutes the Lord’s Supper—it has been a theme from the days in the Garden of Eden when He walked and talked with His people.
We want to control things and we desire to partner with God in all manner of things, but of course, the LORD is in control. He takes care of things and He does not need our help in these matters.
God is in control, but God is also in relationship with His children and asks us to pray, to lament, and to ask Him to change His mind as we participate as the Bride with our Bridegroom.
