How do we know Jesus is capable of saving us?

Jesus Christ is uniquely equipped to save us because of His dual nature. He is God, able to exercise divine power and authority over creation, as seen when He calms the storm in Mark 4:35-41. At the same time, He is also fully human, which means He understands our struggles and weaknesses. This makes Christ the perfect mediator for humanity. His sacrifice on the cross, in which He represented us, along with His resurrection, confirms that He is capable of saving us from sin and death, offering peace and reconciliation with God.
