How do we know Jesus Christ is the rider of the white horse?

The rider on the white horse in Revelation is universally understood to be Jesus Christ because of the characteristics he embodies, particularly His authority and ability to conquer. The text indicates that He goes forth 'conquering and to conquer,' a phrase that aligns with Christ's mission on Earth and His triumph over evil. In the context of Revelation 19:11, the description of Christ as 'faithful and true' further emphasizes His righteous character. As believers, we understand that Christ is the ultimate victor who has already won the war against sin and death, thereby confirming His role as the rider of the white horse.
