How do we know that Jesus is the source of eternal salvation?

The text indicates that Jesus achieved perfection through his suffering, which enabled him to become the source of eternal salvation for all who obey him (Hebrews 5:9). This obedience was not due to sin but stemmed from his complete faithfulness to the Father's will. Therefore, Jesus’ role as the high priest is integral to understanding that salvation is secured in him alone, not through our works or human rituals. He is the only legitimate source of eternal salvation, as he fully satisfies the demands of God’s justice for his people.
