Why is the concept of Christ as our captain important for Christians?

Jesus is referred to as the captain of our salvation in Hebrews 2:10, emphasizing His leadership and authority over our spiritual well-being. This concept reassures believers that, just as Joshua was guided by the captain of the Lord's army, we are led by Christ in our spiritual journey. His victory over sin and death guarantees our eternal welfare. The understanding that salvation is His work alone fosters reliance on God’s grace rather than human effort, which is central to Reformed theology.
