The Bible tells us that the goal of our faith is the salvation of our souls (1 Pe 1:8). If we believe in God but fail to be saved, our faith is in vain and we will be the most pitiful people in the world. The Bible says that the only place where the unsaved people will go is hell a place of eternal torment. So, we need to take the matter of our salvation seriously.
Christs relation to His people is often represented by the figure of a shepherd ( John 10:14, Hebrews 13:20, 1 Peter 2:25, 5:4 ), and therefore the opinion that He is the Lord here so described, and in Genesis 48:15, Psalms 80:1, Isaiah 40:11, is not without some good reason.
