How do we know that Jesus is able to save us?

The evidence of Jesus' ability to save is found in the numerous accounts of His miraculous deeds and teachings throughout the Gospels. Particularly in Matthew 8:1-3, Jesus confronts the uncleanness of leprosy with a simple yet powerful declaration that not only heals the physical condition but also signifies His authority to forgive sins. Furthermore, John 20:31 states that these miracles are recorded so that we might believe in Him, affirming that belief in Jesus leads to life through His name. This assurance underlines that Jesus saves because He actively fulfills the will of God, and He does it fully and completely, which means we can trust in His ability to redeem us from sin.
