How do we know that Jesus is our captain and Savior?

Jesus is depicted as our captain in various passages, including Hebrews 2:10, which states that it was fitting for God to bring many sons to glory through Christ, the founder of their salvation. His role as Savior is confirmed in the fulfillment of Old Testament prophecies, such as Isaiah 53, which speaks of Him bearing our sins. Furthermore, His victory over sin and death through the crucifixion and resurrection establishes His lordship and our reliance on Him for salvation. In Judges 11, Jephthah is portrayed as a type of Christ, coming to deliver those in need, mirroring how Christ offers Himself as our deliverer and captain.
