Christ's glorious Second Coming, surrounded by the Choirs of the Holy Angels and the Saints (source)

  
O, how awesome will Your Second Coming be, as was foretold by the Prophet Daniel, when he said: Thrones were set up, and the Ancient of Days came and sat, being led in by the myriads of the Angels, which stand around in fear and ceaselessly cry out with their voices to the Trinity, unto the ages of ages.

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
