How do we know Jesus Christ was both God and man?

The dual nature of Christ as both God and man is critical to understanding His role in salvation. Scripture affirms this truth, stating in Hebrews 4:15 that He was 'in all points tempted like as we are, yet without sin.' This highlights His humanity, as He shared in our experiences. Concurrently, Colossians 2:9 confirms that 'in Him dwelleth all the fullness of the Godhead bodily,' revealing His divine nature. Hence, His identity as both God and man is essential for redeeming mankind, acting as our representative and sin offering. Without this union of natures, the salvation He provides would be incomplete.
