Colossians 2:5

5 For though I am away from you in body, yet I am with you in spirit, delighted at the sight of your [standing shoulder to shoulder in such] orderly array and the firmness and the solid front and steadfastness of your faith in Christ [that leaning of the entire human personality on Him in absolute trust and confidence in His power, wisdom, and goodness].

This is one of the things that I think about all of the time. The Bible tells us that we worship our Father in Spirit and in Truth.

A time will come, however, indeed it is already here, when the true (genuine) worshipers will worship the Father in spirit and in truth (reality); for the Father is seeking just such people as these as His worshipers. John 4:23

I think that we far too often believe that we have to physically be in each others presence to truly be connected. The Truth is that we are spirits and our spirits are one with each other. The Bible tells us that we are as Jesus is, even while we are on this earth. Jesus has a body, it was raised from the dead and is now in Heaven with our Father. Jesus has a Spirit and that Spirit now lives within us. We too have a body, it is here on the earth, and we too have a spirit, a spirit that is one with Jesus’ spirit. So that means that we are connected with each other just as Jesus is connected with us. We are connected all of the time with each other. We don’t have to physically be in the same room to communicate. We don’t need phones, the internet, or any physical communication to be connected and unified. Think of the power and unity that this gives us. According to Jesus our unity in the Spirit is the power that will allow the world to actually believe and be set free.

That they all may be one, [just] as You, Father, are in Me and I in You, that they also may be one in Us, so that the world may believe and be convinced that You have sent Me. I have given to them the glory and honor which You have given Me, that they may be one [even] as We are one: I in them and You in Me, in order that they may become one and perfectly united, that the world may know and [definitely] recognize that You sent Me and that You have loved them [even] as You have loved Me. John 17:21-23

Wherever two or more of us are, there Jesus is in the midst of us. Our glory is that we are always with two or more. We are always with millions upon millions. Whether we are alive or dead makes no difference, we are always perfectly connected and unified with the entire body of Christ.
