The certainty of Jesus' second coming is affirmed through the Scriptures, which prophesy His return and outline the signs of the end times.
We know Jesus' second coming is true because of the prophetic nature of Scripture that speaks of His return with great authority and power. Matthew 25 provides a vivid depiction of this event, where Christ emphasizes that He will come to execute judgment. The prophecies in the Old Testament foretold the coming of the Messiah, and, likewise, the New Testament assures that He will return to fulfill all that was promised. Additionally, His resurrection validates His sovereignty and ability to perform all His declarations, including His second coming.
