He came as a conqueror with the gladness of the imminent victory in His heart; for the joy set before Him He was able to endure the cross, despising shame (Hebrews 12:2).
He exulted in the Holy Spirit (Luke 10:21) as He contemplated the ways of God in bringing many sons to glory. The word (exulted) is a strong one and conveys the idea of exuberant gladness, a gladness which fills the heart. –BB Warfield
