Christ is Three Shepherds:
The Good Shepherd (John 10:14-15) - speaking of His death
The Great Shepherd (Heb. 13:20) - speaking of His resurrection
The Chief Shepherd (1 Pet. 5:4) - speaking of His glory
The Three appearances of Christ:
Past: Has appeared (Heb. 9:26) to put away sin
Present: Is appearing (Heb. 9:24) in the presence of God
Future: Will appear (Heb. 9:28) to those who await Him
The Father spoke from Heaven three times:
Matt. 3:17, "This is My beloved Son, in whom I am well pleased."
Matt. 17:5, "This is My beloved Son, with whom I am well-pleased; listen to Him."
John 12:28, "I have both glorified it [the Father's name], and will glorify it again."
