How do we know Christ's appearances throughout the Bible are true?

Scripture provides extensive evidence of Christ's appearances, affirming His divine nature and role as our Savior. In the Old Testament, He appeared to patriarchs and prophets, both in visions and incarnate forms, aligning with the prophecy and typology presented in the scriptures. For instance, John 8:56 illustrates Christ's statement about His existence before Abraham, affirming His eternal nature. The New Testament further confirms these truths by documenting His life, death, resurrection, and ascension, providing a complete picture of His fulfillment of the law and the prophets.
