Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. (1 Peter 5:8). That roar can affect your perception of the situation. If you focus on the roar, you will forget who you are in Christ and the promises that are already yours. But, the Word of God does not fail! God does not lie!
Stop accepting every diagnosis and the names that doctors give you and the prophecies they tell you about diseases in your body--the Word of God supersedes ALL of it. (See Isaiah 53:5)
It has never been as important as it is RIGHT NOW that you learn how to resist the enemy and take territory for God.
Remember, Jesus killed a fig tree with His words of authority and brought Lazarus out of the grave with that same authority. Your words have that same authority. Don't fear that authority. Rejoice in it. Speak the good things. Decree provision, healing, direction, wisdom and health.
