This episode focuses on Isaiah 6, which opens with a national crisis that drives Isaiah to the temple, where he receives a life altering vision of the Lord that reveals Christ’s transcendent holiness and sovereign rule. After the temple is shaken by the seraphim, a seraph touches Isaiah’s lips with a coal from the altar—symbolic of the cleansing provided through Christ’s future sacrifice. When God asks, “Whom shall I send?,” Isaiah eagerly responds, “Here am I; send me,” modeling the purpose, humility, and willingness that should characterize all who serve the Lord.
