There are many names for God in the Bible, both names that describe God and names that are titles for God. As I was reading in Psalms, I was struck by a name for God that we don't hear mentioned much, and that is the name "shield." We usually think of a shield as that large piece of metal that a knight in the days of old would hold to protect him from swords and spears, but according to Merriam-Webster, another definition of "shield" is "one that protects or defends." So "shield" is shorthand for a protector and a defender, both of which are attributes of God.
Below are some verses I found that reference God as a shield. These are some of my favorites, but there are more than just these; a search will turn up several other verses.
2 Samuel 22:31 (NLT): God's way is perfect. All the Lord's promises prove true. He is a shield for all who look to him for protection.
Psalm 3:3 (NLT): But you, O Lord, are a shield around me; you are my glory, and the One who lifts up my head.
Psalm 5:12 (NLT): For you bless the godly, O Lord: you surround them with your shield of love. (I really like that verse!)
Proverbs 30:5 (NLT): Every word of God proves true. He is a shield to those who come to him for protection.
Just as we who are earthly parents want to protect our children from anything that might hurt them, God our heavenly Father wants to protect us from danger and harm. Instead of using a large piece of metal to protect us, God Himself surrounds us (see Psalm 3:3 above). Not only does He protect us from physical harm, He surrounds us with a shield of love, as in Psalm 5:12 above. That shield of love comforts us when we are emotionally hurt. When we feel God's presence with us, we are feeling that "shield" that protects us.
