How do we know Jesus' divinity and kingship are true?

The truth of Jesus' divinity and kingship is solidified through various Old Testament prophecies that find their manifestations in the New Testament, particularly in the Gospels. Zechariah 9:9 speaks specifically to the coming of a King who is just and brings salvation, which was fulfilled during Jesus Christ's triumphal entry into Jerusalem. The historical reliability of these prophecies, coupled with Jesus' life, death, and resurrection, affirms His identity as both Savior and King. In addition, the continuous witness of the Holy Spirit within the hearts of believers assures us of Christ's authentic kingship and divine essence, as stated in John 16:13, where the Spirit of Truth guides us into all truth about Him.
