^3:20 Look, I’m standing at the door and knocking. If anyone listens to my voice and opens the door, I’ll come in and we’ll eat together.

Look, I’m standing at the door and knocking.

This is the door of the church at Laodicea (or your church) and not necessarily the heart's door as so many evangelists use this verse. This would indicate that there either were lots of deaf Christians or lazy Christians ignoring the knocking. (Or, there is so much "noise" within the church that the knocking is drowned out (1 Kings 19:11-13)). The same question Elijah heard is appropiate for each one reading this: "WHAT ARE YOU DOING HERE, (fill in your name)?"

Note, too, that Christ is outside the church (Hebrews 13:12-13). We can go outside the church to be with him individually OR the members of the church can invite Him in to be with them. He would prefer to come inside because He says

If anyone listens to my voice and opens the door,

There had to be some life in the church in order to hear the knock and OPEN the door - John 5:24-29 and John 10:24-30. Opening the door is the act of repentance and discarding all fleshly things (Galatians 5:19-21).

I’ll COME IN and we’ll eat together.

As we sit down to eat with Him (His word), the use of "we'll" implies that the relationship is just not Jesus and us. The "table" is set for the fulness of the Holy Trinity and US. His Spirit is there as He shares His food (bounteousness of the Father). Then we grow and become strong believers. Thus begins the beautiful relationship between the believer and the Holy Trinity (Colossians 3:15-17). One note of warning: James 5:9 indicates those who don't open the door will face the Judge!
