How do we know Jesus is able to save us?

The knowledge of Jesus’ ability to save stems from His identity as the promised Redeemer throughout Scripture. In the account from Matthew 9, the blind men refer to Him as 'Son of David,' recognizing Him as the messianic figure who has the authority and power to heal and save. The cumulative testimony of the Old Testament prophesies, along with the miraculous works and teachings of Jesus, confirms that He is indeed able to save those who come to Him in faith. His ministry was characterized by acts of mercy and forgiveness, pointing to His unique role in God’s redemptive plan.
