Green is the predominant colour to contrast with the reds of the Workington Window.

The main subject is the parable of the Prodigal Son, showing his reconciliation with his father in the central light.

The cross runs through the design, a green living cross which grows into the Tree of Life as described in the Book of Revelation with the twelve different fruit and quotation "The Leaves of the Tree were for the Healing of the Nations" in the tracery lights.

On either side of the main figures are other scenes from the parable i.e. on the left, the son in despair looking after the pigs, on the right, his welcome home with the fatted calf being brought out.

The flames at the base of the window represent war being superseded by the peaceful colours on the rest of the window.

The upper part of the side lights shows the two major sacraments of Baptism and the Eucharist.
