How do we know that Christ is the spotless Savior?

The concept of Christ as the spotless Savior is foundational to our faith. He lived a sinless life and was declared holy and blameless, highlighted in verses such as Hebrews 4:15, which reminds us that He was tempted in every way yet without sin. The importance of Christ's purity is significant because, without it, He could not serve as our substitute or redeem us from our sins. Hence, His sinless nature qualified Him to be the spotless Lamb of God who takes away the sins of the world.
