As I been going through some rough times with a lot of spiritual warfare, I've been finding my comfort from the promises of our God in his Word. Everytime the enemy lies to me I start reminding him and myself of the promises of God. Not only does it build my faith, but after repeating and thinking about the scriptures I find that he flees, which is another promise of God: James 4:7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
As I submit in believing and also resist in believing, the devil flees from me. Then I have a period of peace before the enemy finds another opening. Without the word of God, I'm helpless. Praise God for his word and thank him for victory in Christ Jesus.
