. . .the battle is not yours, but God's. II Chronicles 20:15 (NKJV)
When the enemy comes in like a flood, The Spirit of the Lord will lift up a standard against him. Isaiah 59:19(c) (NKJV)
There's more, but you get the idea. This song bears a powerful message to help us better understand what the Word of God has already shown us. In II Chronicles chapter 20 God spoke through a Levite name Jahaziel, telling all of Judah the battle with Moab, Ammon, and Mt. Seir did not belong to them, but to God. The same is true today; whatever battle the enemy has waged against you, the battle is still not yours, but the Lord's. Spiritual warfare is that invisible conflict going on in the spirit realm, but it affects the human realm - we see it in different ways in our everyday lives. It can take many forms, i.e., trouble in marriages, family relationships, discord in the church, confused minds, and the list goes on and on.
But what does being sanctified have to do with spiritual warfare? Everything! To be sanctified means to be "set apart." So when you have set yourself apart to bring God glory, you'll approach spiritual warfare differently than the person who has chosen to live life his or her own way. When you have a sanctified mind, every area of your life is lined up under God's authority. So when the enemy does come, and he will, your response will be praise; you will respond in worship because you understand where your power is. You can praise your way through periods of spiritual warfare because you know that God is all powerful over anything the enemy can throw your way. A sanctified heart will pray without ceasing (I Thess. 5:17), praise God all the time (Ps. 34:1), and be careful to wear spiritual armor (Eph. 6:10-17). Not only will you wear your armor, but you will understand why Paul was so adamant in teaching us about it. God knew the challenges we would face when we chose to follow Him, but He didn't leave us with no weapons to fight. Spiritual warfare is a reality in our Christian experience. Keeping the praises of God ringing in your heart and in your mouth is just one of the ways we can stay strong in the battle.
