The words "major entrance," visible in the sky, are part of the architectural blueprint that underlies the original piece. The use of the blueprint recalls the Scripture, "We long for a city whose architect and builder is God." Grace descends from heaven and the entrance to the Father’s house to intersect the prodigal figure's back. It forms a cross with the earth. The fence posts suggest the three crosses of Golgotha, and the body of the prodigal suggests the buried seed, Christ, who descended into the darkness of the earth.
