Because He alone was Perfect, even Death couldn’t Kill Him nor could Hell hold Him.
“Lord Jesus Christ, Son of the Blessed One”
“But Jesus remained silent and gave no answer. Again the high priest asked Him, “Are you the Messiah, the Son of the Blessed One?” (Mark 14:61)
Christ Answered it “not” in Words, but in Action by Resurrecting back to Life, proving Who He is once and for all.
