Boy! That would be good if that was the end of the sentence, but unfortunately it is not. The passage say for we wrestle not against flesh and blood, let’s read the whole passage:
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. Ephesians 6:10.
For those of us who have been born again; saved, have eternal life residing on the inside of us, if we have received the revelation of that being born into the greatest conflict ever, we have a chance to gain the mastery over it. And if we were taught that you must cleave to God through his word and act upon everything you learn. There are two realms: the Kingdom of God and the Kingdom of Satan. Satan was ousted from his position prior to man’s creation, and is all about disrupting the lives of God’s man. Paul said when I would do right evil is present to attempt to throw me off. Thus the wrestling in the mind, in the will, and in the emotions. James says, submit yourself therefore unto God, RESIST the devil, and he will flee from you. These terms bring to light that we are not to be passive, but actively wrestling, resisting, by taking a stand upon the word.
Once you understand that you can’t just say,” whatever will be, will be,” then you will enter into the place where you can contend for the faith.
Ephesians 6:10-16
10 Finally, my brethren, be strong in the Lord, and in the power of his might.
11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15 And your feet shod with the preparation of the gospel of peace;
16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
James 4:7
