We know that Jesus is coming again because He has promised it in scripture, affirming it through His teachings.
The assurance of Jesus's second coming is found throughout the New Testament, particularly in passages like Mark 13:26 and Revelation 1:7, where He promises that all will see Him when He returns. This is not merely a prophetic statement but a promise backed by His authority and empowerment. Additionally, the signs described in scripture, such as cosmic disturbances and the final gathering of His people, reinforce the certainty of His return. Believers are encouraged to keep this hope alive in their hearts, as it is essential for their spiritual well-being and motivation in life.
