When we feel afraid...and we will...we must speak the Word of God. The Word of God is a weapon (Ephesians 6). It is the one thing that not only causes the enemy to flee, but it also releases the power and authority of God to be activated in our lives. When Jesus was tempted by Satan in Matthew 4, He spoke the written word of God. Satan fled the scene because he hates hearing the word of God!
It is important to decree and speak the word of God over our lives aloud. Words are spirit and life. When we speak God's word, we speak life into our situation. Psalm 27:1 is of course a song, but it is also a decree. When we read this verse aloud we are decreeing that the LORD is our light, our salvation, and our stronghold--our place of refuge, safety, and protection. He is the Lord of Hosts. He is the God of war, Jehovah Gibbor. He is almighty and all-powerful.
Remember the prophet, Elisha and his servant in 2 Kings 6? The King of Syria was furious that his war plans had been revealed to Elisha by God. So, at night, he dispatched a mighty army with chariots and horses to surround the city where Elisha was. All of this for one man!
When Elisha's servant got up early and saw the encampment, he was terrified. (And rightfully so. Can you imagine waking up to that scene?) He asked the prophet, "What are we going to do?" Elisha said something interesting and prayed something interesting. He told his servant not to be afraid because there were more with them, than with the enemy king. Then he prayed that the Lord would open the servant's eyes so that he could "see". And the Lord did just that, he opened the servants eyes so that he could see the mountain full of horses and chariots of fire dispatched by God, the Lord of Hosts! The enemy was surrounded and ultimately defeated!
God reigns supremely. Satan is in no way equal to God. There is no power struggle here. The enemy is defeated! Because of this truth, we do not have to live in fear. We are fearless!
Father, in the name of Jesus, I thank you for the truth of your word. I thank you that because you are my light and my salvation, I will not be afraid. I decree that you are my fortress, my refuge, my strong tower according to your word in Psalm 27. Therefore, I decree courage, peace, and fearlessness in my life. Amen.
