HERE is a link to an online version of Psalm 3.
Enemies come in many shapes and sizes. David literally had thousands of people seeking to destroy his life. He struggled to let his head lay back and close his eyes for fear he would wake to a spear though his chest. I am not a man who has an army of soldiers trying to kill me. But I do (as you do) have an enemy who prowls around like a roaring lion seeking to devour my faith (1 Peter 5:8). That enemy is the devil, the father of lies. When this enemy surrounds us seeking to wreck our joy, our families, and our faith; we need a shield of protection.
A shield bearer was a trusted and faithful person who never left your side in the heat of battle. A person who went before you and was willing to lay down his life in order to save yours. Psalm 3 tells us that the Lord is a shield about me. He arises and saves. He goes into battle with us and not only defensively protects us, but goes on the offensive and “strikes our enemies on the cheek” and “breaks their teeth”. He “arises” and “saves” us when we “cry aloud to him”.
Salvation and deliverance belongs to the Lord and this blessing is “on his people”. Jesus Christ is the one who has gone to battle for his people. He is our shield and armor bearer who laid down his life for his sheep. He is more than a shield to us. After he laid down his life for our protection, he rose from the dead proving once and for all our enemies were defeated at the cross. Jesus now is the one who is “our glory” and the “lifter of our head”. We can walk in victory over sin and Satan today because deliverance belongs to Jesus and his blessing IS ON HIS PEOPLE.
