How do we know that the second coming is true?

The truth of the second coming is founded upon the authority of Scripture, which contains numerous prophecies that validate God's promises. Jesus Himself spoke of His return in multiple passages, especially in Matthew 24 and Revelation, assuring His disciples that He would come again. The fulfillment of Old Testament prophecies about His first coming provides a strong basis for faith in His second coming, as Jesus’ first advent happened precisely as foretold, demonstrating God's faithfulness. Hebrews 9:28 states that 'Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.' The consistency and infallibility of God's Word reinforce our trust in the certainty of Christ's return.
