The radio of the heart: space cannot separate us

Please read the letter, I wrote it in my sleep / With help and consultation from the angels of the deep / Please read the letter that I wrote... (Alison Krauss and Robert Plant, "Please Read the Letter")

… Don't need no phone at all / We've got a thing that's called radar love / We've got a wave in the air / Radar love! (Golden Earring, “Radar Love”)

There is a letter sent by St. Porphyrios (on Mt. Athos in Greece) to St. Sophrony (in Essex in England) that goes

Elder Sophrony, 

I embrace you in Christ. 

A certain person told me that you would like to have us meet; that you’ve invited me to come to England and if I cannot go there, you will come to Greece. 

Since it is impossible for me to come, and I do not wish you to go to the great trouble of travelling here, and since Christians cannot be separated by distances, we could meet one another in prayer by saying, ‘Lord Jesus Christ have mercy on me’... (St. Porphyrios, letter to St. Sophrony)

It was later confirmed that the two were meeting each other in prayer: 

In November 1990, we had the privilege of meeting Elder Sophrony in Essex and talking to him. He told me that he used to meet Elder Porphyrios in prayer every night. They each knew what the other one looked like, even though they had never seen one another with their physical eyes. Elder Porphyrios had never seen Elder Sophrony, and vice versa. (Elder Porphyrios: Testimonies and Experiences)

The heart can communicate things in secret between people. It is the radio by which we listen to God, and pray to the saints, and meet in prayer with another. The Holy Spirit, God Himself, is an invisible strand which connects believers; He is our phone line, if you will.

Yes! We do not really need physical communication at all. Or, just as we communicate through physical energy—through light, radio waves, for example—so it is possible to communicate through God’s energies—through the divine light.

Even if matter, space and time should keep us apart, we are yet not separated from one another. There is nothing that the dark spiritual and earthly powers can do to keep us truly apart. This world and the flesh have no power over those who have found rest in God—a rest which is found within the heart. One only needs to look with the eye of the heart, and listen with the ears of the soul, in order to see and hear another.
