All the World has been Enlightened and Sanctified by the Lord's Baptism

When Thou, O Lord, wast baptized in the Jordan the worship of the Trinity was made manifest! For the voice of the Father bare witness to Thee, calling Thee his Beloved Son. And the Spirit, in the form of a dove, confirmed the truthfulness of his Word. O Christ our God, who hast revealed Thyself and hast enlightened the world, glory to Thee (Troparion).http://oca.org/orthodoxy/the-orthodox-faith/worship/the-church-year/epiphany
Today Thou hast appeared to the universe, and Thy Light, O Lord, has shone on us, who with understanding praise Thee: Thou hast come and revealed Thyself, O Light Unapproachable!
(Kontakion) from the same source.

The Lord has appeared on earth as long foretold and He has left his footprint, Sanctification and great mercy.

Epiphany, celebrated in January, is a time when believers accept into their homes the blessed water, keeping some in reserve for when we need refreshment. There have been stories of healing from people who drink blessed water, and as well as, enjoy victory over other situations, like storms, protection and the granting special favors.

 My little grandson, says "get the holy water out" I'm sick, and runs to the refrigerator.

The voice of the Father bore witness to You Jesus, and Spirit in the form of a dove confirmed the truthfulness of His word. When You were baptized in the Jordan, enlightening and sanctifying the entire world. During Holy Week we hear the words sung from the troparion of Cassiane, "O thou Who dost gather into clouds the water of the sea." Vesper services begin with Psalm 103 which give us the beautiful image of creation, "The waters stood above the mountains" and "Thou makest springs gush forth in valleys, they flow between the hills." Waters permeating the entire planet, evaporating and flowing from Jesus who once stood in the river Jordan, refreshing us all and, all creation for all time. I recall reading that the waters "turned back." because they were afraid, identifying Jesus in the Jordon.

Christians live in blessed assurance and hope, for Christ came into the world to save us. He is still with us and will return as He promised. Revelation 21:4  "And God will wipe away every tear from their eyes;" Taken from the Orthodox Study Bible
