Walking through Lent the Church gives us key glimpses, that is, tastes through the liturgical narrative leading to Pascha (Easter).
The icon shows Lazarus being untied of his burial shroud. In fact, this metaphor of being untied is key: the crucified and risen Lord unties us of our sin to live in freedom.
A hymn at Lenten Vespers is revealing:
“O Lord, while dwelling in the flesh on the other side of Jordan, Thou hast foretold that the sickness of Lazarus would not end in death, but that it had come to pass for Thy glory, O our God. Glory to Thy mighty acts and Thine all-sovereign power, for Thou hast destroyed death in Thy great mercy and Thy love for mankind.”
