What does it mean to say Jesus was sinless?

The sinlessness of Jesus is a foundational truth in Christian theology. As stated in the sermon, He was the 'spotless Lamb' without blemish or defect, fulfilling the required standards of righteousness needed for atonement. Scriptures such as 1 Peter 2:22 affirm that He committed no sin and that no deceit was found in His mouth. His sinless life qualified Him to bear the sins of many and serve as our high priest. Without His sinlessness, He would not have been an acceptable sacrifice for the sins of humanity.
