How do we know that Christ is the only pure one?

The uniqueness of Christ’s purity is evident throughout the New Testament. Hebrews 4:15 states that Christ was 'tempted in every way, just as we are—but was without sin.' This underscores that He is the only perfect and spotless human to have walked the earth. Throughout Matthew and other scriptures, it is clear that while humanity attempts to strive towards purity, no one can achieve this without the efficacious work of Christ. His life and death were indispensable in establishing the righteousness and purity required for salvation, making Him the exclusive mediator between God and humanity.
