2Co 10:4 (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
2Co 10:5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
Dominion for the disciple includes bringing every thought into captivity and making it obedient to Christ.
Every thought is to be controlled and lined up with the Word Of GOD.
When Satan injects thoughts of doubt or fear, they are to be brought into captivity and cast out with the Word of GOD.
When he tempts you to fear just stop and say:
2Ti 1:7 For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
A fearful mind is not a sound mind. Rebuke fearful thoughts.
A doubtful mind is not a sound mind. Cast out doubts with the Word of Christ.
Our minds are not to be garbage containers. If they are, our thoughts will be manifested in our words and actions.
Do not entertain evil thoughts.
The devil may inject an unclean idea or a negative thought into your mind, but you do not have to allow it to stay.
Do not pet it and toy with it. Cast it out immediately and replace it with a thought that meets all these scriptural criteria:
Php 4:8 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
If a thought is not true, honest, just, pure, lovely, and of good report, simply refuse to allow it to stay in your mind.
This is an area where every disciple can and must assert dominion.
You can bring into captivity every wild and unspiritual thought.
