Principles from The Art of War by Sun Tzu
All warfare is based on deception, therefore:
When capable, feign incapacity;
When active, feign inactivity
When near, make it appear that you are far away
When far away, that you are near
Offer the enemy a bait to lure him in;
Feign disorder and strike him
When he concentrates, prepare against him;
When he is strong, avoid him
Anger his general and confuse him;
Pretend inferiority and encourage his arrogance
Keep him under a strain and wear him down.
When he is united, divide him
Attack where he is unprepared;
Sally out (erupt or bust out) when he does not suspect you.
These are the strategic keys to victory.
And these keys will be used by the Enemy against all those who are moving forward in the Plan of God for their lives. It's important to remember these things, so we can be aware of them when they are used against us .
2Co 2:11 ... so that no advantage would be taken of us by Satan, for we are not ignorant of his schemes.
