The Greek noun anadeixis means "public presentation" or "official manifestation." It appears once in Luke 1:80, referring to John the Baptist's public appearance to Israel.
Luke records that John lived in the wilderness "until the day of his public appearance (anadeikseōs) to Israel." This captures a theological rhythm: the preparation in hiddenness precedes the public commissioning. Moses was in the desert forty years. David tended sheep before the throne. The Son Himself spent thirty years in obscurity before His baptism. Formation always precedes anadeixis.
