How do we know Jesus is an able Savior?

In Matthew 8:1-4, Jesus' command and immediate response to the leper illustrate His divine ability to heal and cleanse. When He said, 'I will; be thou clean,' the leprosy was cleansed immediately. This reveals not only His willingness but also His sovereign power over physical and spiritual maladies. The broader context of Scripture supports this, showing that Jesus possesses the authority to forgive sins, suggesting that His power extends beyond physical healing to spiritual redemption, emphasizing His unique position as the divine Savior.
