How do we know Jesus has the power to save?

The confidence in Jesus' saving power is established through His divine authority as presented in the Gospels. In the passage from Mark 5, we see Jesus commanding demons and restoring the man, showing His control over spiritual forces. This power to save is echoed in John 6:40 where Jesus states that all who see Him and believe will have eternal life. These miracles are not just acts of compassion; they affirm His identity as the Son of God, who has the sovereign right to forgive sins and offer salvation. The relationship one has with Christ, recognized through faith, is assured by the Transformative work He does within each believer, making His ability to save not only a theological assertion but an experiential reality.
