Heb 2:10 For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings.
Jesus is the captain of our salvation. What does that mean? Captain is not just a title for a commander in chief of an army, but it has the idea of a brave commander who goes ahead of a group of soldiers to lead the way. In other words, Jesus is the Captain who has paved the way so that He can lead His army into freedom and salvation.
How does Jesus lead the way to salvation? By fighting our enemies for us. Sin is our greatest enemy. We are to kill it, before it kills us. It is a cruel enemy. But we cannot kill sin unless we follow our Captain of salvation in faith. He has entered the battlefield on behalf of his army, a band of weakly sinners, and He has won the victory and paved the way to salvation and freedom.
Think of David and Goliath. Goliath was a cruel killer. None could conquer him, all trembled at him. Except for David. He fought and won the battle on behalf of his people. So, also Christ, he led the way where we could have never won the victory. Now He calls us to follow His lead, kill sin, in His power, knowing that He already crushed satan’s head. Only when we are strong in the Lord and the power of His might and take from Christ the whole armor, we will be led to full salvation! His full salvation is our full protection. Trust His salvation!
