While speaking of His Second Coming, Jesus Christ said, "Heaven and earth will pass away" (St. Matthew 24:35). The psalmist King David says that heaven and earth will perish: "They shall perish, but Thou shalt endure; yea, they shall all wax old as a garment, and as a vesture shalt Thou change them, and they shall be changed" (Psalm 101:27). God will change and renew all of the creation by means of fire, just as the earth was renewed at the time of the flood by means of water...

The word of God reveals to us some signs of the approaching end of the world and the glorious Second Coming of Christ. Physical nature will then be characterized by famine, earthquakes, epidemics, and other particularly terrible manifestations of the powers of nature, as well as various signs in the sky (St. Matthew 24:7).

"It is the day of the Resurrection; let us be glorious in splendor for the festival, and let us embrace one another. Let us speak also, O brethren, to those that hate us, and in the Resurrection, let us forgive all things, and so let us cry: Christ has risen from the dead, by death, trampling upon Death and has bestowed life to those in the tombs. Christ has risen from the dead, by death trampling upon Death, and has bestowed Life to those in the tombs.

On Bright (Diakainisimos) Friday our Holy Orthodox Church celebrates the feast-day of the Life-Giving Spring of the Theotokos (Η Ζωοδόχος Πηγή). This holy day is referred to as a "movable" holy day of the ecclesiastical calendar.  

"Christ is risen, and the Angels rejoice, Christ is risen, and life is liberated. Christ is risen, and the tomb is emptied of the dead; for Christ, having risen from the dead is become the firstfruits of those that have fallen asleep. To Him be Glory and Power forever and ever. Amen." (St. John Chrysostom)

Bright or Renewal or Diakainisimos Week is the first week following the Resurrection of Our Lord and Savior Jesus Christ, which is celebrated each year at Pascha. It ends the following Sunday of Thomas. Each day is referred to as: Bright Monday, Bright Tuesday, Bright Wednesday, etc. It is possible that the name was given because it marked the beginning of the new period of spiritual renewal for the faithful (catechumens) who were baptized on the evening of the Holy and Great Saturday.
