The truth of the Word of God is evidenced through its eternal nature and fulfillment in Christ.
The assurance of the Word's truth lies in its incorruptible nature. It was spoken by God, and as Hebrews 4:12 affirms, it is living and active, sharper than any two-edged sword. The Word transcends man-made wisdom and is witnessed throughout scripture. Furthermore, Christ is the literal embodiment of the Word (John 1:14), fulfilling all prophecies and promises of God, which reinforces the certainty that the Word is true and reliable.
