Why have we been given the icon of the Divine Heart of God the Father – an icon of a heart and Person generally invisible in nature, in comparison to the incarnate Son of God who visibly took on our humanity? Because “visible things in so far as they represent invisible things without shape so that in giving the visible things a physical shape, we can have a veiled knowledge of them . . . the mystery of the Trinity is reflected in the sun, its light and its rays” (Egon Sendler, 1988, The Icon: Image of the Invisible, p. 80).
