Jesus performed nine miracles in Matthew 8 and 9, demonstrating His divine authority over people, spiritual powers, and nature. These miracles weren't random acts but purposeful displays of His identity as the Messiah. When Jesus healed Peter's mother-in-law, she immediately began serving Him, showing that God's healing should lead to faithful service. While physical healing is wonderful, the greatest miracle is spiritual transformation through salvation in Christ. Every believer can experience this miracle of forgiveness and eternal life, regardless of their physical circumstances.
