St John of Kronstadt: When you are praying alone, and your spirit is dejected...

When you are praying alone, and your spirit is dejected, and you are wearied and oppressed by your loneliness, remember then, as always, that God the Trinity looks upon you with eyes brighter than the sun; also all the angels, your own guardian Angel, and all the saints of God. 

Truly they do; for they are all one in God, and where God is, there are they also.

St John of Kronstadt
