How do we know that Christ's divinity is true?

In John 20:28, Thomas addresses Jesus as 'My Lord and my God,' and rather than rebuking Thomas for this proclamation, Jesus affirms it, which serves as a clear testament to His divinity. This moment not only reveals Jesus's acceptance of divine honor but also establishes a critical foundation for Christian doctrine regarding the nature of Christ. Throughout Scripture, Jesus's works, such as His miracles and His role in creation (John 1:1-3), combined with the prophetic fulfillments of His life, point to His divinity. The acknowledgment of Christ's dual nature as fully God and fully man is essential for understanding His role in atonement and salvation. Without His divinity, the entire framework of redemption collapses.
