What does the Bible say about miracles and their purpose?

In the Bible, miracles serve the purpose of confirming who Jesus is, demonstrating that he is the Messiah foretold in Scriptures. For example, when John the Baptist doubted, Jesus told his disciples to report back to him that the blind see and the lame walk, which affirmed his messianic identity (Matthew 11:4-5). Miracles were not merely acts of compassion; they were intended to reveal Jesus' divine authority and mission to save sinners. Thus, every miracle is a testament to his power and willingness to deliver us from sin.
