We know Christ's coming is true through the fulfillment of Old Testament prophecies and the testimony of the New Testament writers.
The truth of Christ's coming is supported by numerous Old Testament prophecies that point to His arrival, such as the prophetic message found in Isaiah and the promise articulated in Genesis 3:15. Additionally, the New Testament writers, including John, declare that Christ was manifested to take away our sins and defeat the devil's work. The resurrection of Jesus further affirms His victory over sin and death, underlining the credibility of His coming as foretold by Scripture and experienced by the early church. Faith in these truths is anchored in both the reliable witness of Scripture and the transformative experience of those who encounter Christ.
