How do we know Jesus' title of the Son of Man is important?

The title 'Son of Man' is crucial because it speaks to both Jesus' identity and His mission. In Matthew 9:6, Jesus, as the Son of Man, claims authority on earth to forgive sins, asserting His divinity while also connecting with humanity. This duality is fundamental in understanding His purpose: to seek and save the lost (Luke 19:10). His designation not only affirms His human experiences but also His divine prerogative in redemption, showing that He came to fulfill the Father's will by securing eternal life for His elect.
