How do we know the necessity of Jesus as our Redeemer?

The necessity of Jesus as our Redeemer is rooted in the doctrine of sin. Psalm 49 highlights that no wealth or power can redeem a soul. All humans, being descendants of Adam, are spiritually impoverished and incapable of redeeming themselves due to the weight of sin. Only one who possesses both the right to redeem and the means to do so can act as a Saviour. Christ, being God incarnate, had the necessary qualifications—He is the only one who could fulfill the righteous demands of God’s law. His unique ability to redeem comes through His perfect obedience and sacrificial death, establishing Him as the sole Redeemer of His people.
