What does the Bible say about Jesus healing on the Sabbath?

In the Gospel of John, Jesus addresses the issue of healing on the Sabbath, which the Jews used as a basis to accuse Him. He points out their hypocrisy by emphasizing that they circumcise on the Sabbath to uphold the law, yet they seek to kill Him for healing a man. This act demonstrates the failure of the religious leaders to understand the true spirit of the law, showing that preserving human life is greater than strict adherence to rules. Jesus' assertion highlights that He is the Lord of the Sabbath, thus possessing authority over it, and His miracles are acts of compassion rather than law-breaking.
