Submit yourselves therefore to God. Resist the devil, and he will flee from you. James 4:7
Yes, resist the devil and he will flee, but you have to be submitted to God.
There are many scriptures that reflect that God is stronger and God does protect us from Satan.
There are spiritual conditions to that promise.
If we are choosing to dabble in the occult, that does not give us all power.
We do not own the power that God has. He retains His power that He lends to us.
Satan has power. No place in the bible does it say he does not have power.
Can he exercise his power over us? Not if we are in the perfect will of God. Not if we are protected by God.
For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
Romans 8:2
We have to remain under God’s protection, submitted to Him.
The minute we stray, we are in unchartered territory.
