When you watch a film or read about ancient battles, people usually had two things with them, a sword and a shield. Hand to hand combat was the norm. With one hand they attacked in order to advance, with the other they defended from the bows of their enemy. Shields came in all sizes too. One of the things I think is important to note is that when a shield got struck, the person carrying it felt the weight of the blow. They save your life and protect you from most or all of the damage, but not the pressure. As you hold that shield, you have to exert pressure back toward your opponent so that you’re not overcome.
In the book of Nehemiah, a small group of Jews were rebuilding the walls of Jerusalem to create a shield from their enemies. While building the wall, their enemies tried to persuade them to quit building it. When that failed, they tried intimidation. In chapter 4, the Bible says that Nehemiah had half of the people continue their work on the wall and the other half stand ready for battle protecting the work. They carried swords and shields. The situation was tense. Everyone felt the pressure, but they continued to work. Their enemies saw the swords and shields and chose not to attack. They knew their plans would be thwarted.
Psalm 84:11 says, “The Lord God is a sword and shield” (AMP). Later, Psalm 119:114 says, “You are my refuge and my shield; your word is my source of hope” (NLT). You and I are constantly entrenched in battles because our enemy wants to stop our progress. He tries to intimidate us into stopping, but the Lord is our shield. You’re going to feel pressure in the battle. You’re going to grow tired as well, but stay in God’s Word during those times. As this verse says, the Bible is a source of hope for us when all seems lost. God is fighting for you and protecting you as you continue to do what He called you to. Don’t let the pressure get to you. Find someone who will stand on the wall with you in prayer holding their sword and shield. It won’t be easy to complete, but with God as your shield you can continue.
