How do we know that Jesus' fulfillment of the Scriptures is true?

The truth of Jesus fulfilling the Scriptures is demonstrated throughout His life and ministry. His statements, such as 'I thirst', were not mere expressions of His physical state but profound affirmations of messianic prophecies being realized in Him. Numerous Old Testament prophecies detail the suffering of the Messiah, and Christ’s words on the cross affirm that He completed what was written about Him. This fulfillment is essential in establishing Jesus as the promised Savior, who showcases God's faithfulness as all Scriptures pointed toward Him. His awareness of the Scriptures illustrates His divine authority and the certainty that He came to fulfill the will of His Father.
