“Upon Mount Tabor, Jesus revealed to his disciples a heavenly mystery. While living among them he had spoken of the kingdom and of his second coming in glory, but to banish from their hearts any possible doubt concerning the kingdom and to confirm their faith in what lay in the future by its prefiguration in the present, he gave them on Mount Tabor a wonderful vision of his glory, a foreshadowing of the kingdom of heaven. …
Therefore, since each of us possesses God in his heart and is being transformed into his divine image, we also should cry out with joy: It is good for us to be here – here where all things shine with divine radiance, where there is joy and gladness and exultation; where there is nothing in our hearts but peace, serenity and stillness; where God is seen. For here, in our hearts, Christ takes up his abode together with the Father, saying as he enters: Today salvation has come to this house. With Christ, our hearts receive all the wealth of his eternal blessings, and there where they are stored up for us in him, we see reflected as in a mirror both the first fruits and the whole of the world to come.” ~From a sermon on the Transfiguration of the Lord by Anastasius of Sinai, bishop, 7th Century AD
