Time to suit up
Before you can get into a spiritual battle you need to be fully armored up. The battlefield is littered with many, many who thought they could fight the battle without being fully covered in the armor.
Ephesians 6:10 Finally,
The book of Ephesians is to the church, and it says the church is the Body of Christ, it is the one new man and it is the warrior. No one can fight the spiritual battle alone. We are an army and we are all connected to the head, one with the head, and take orders from the head.
be strong in the Lord, and in the strength of his might.
Do not be strong in yourself, or your opinion, or your might. Jesus is wiser, He has all the treasures of wisdom and knowledge hidden in Himself, and He has built the church to win this war.
11 Put on the whole armor of God, that ye may be able to stand against the wiles of the devil.
You cannot stand against the wiles of the devil if you do not put on the whole armor. This act of "putting on" involves prayer, fellowship, and time in the word of God.
12 For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places.
You cannot wrestle if you don't know who or what you are wrestling. I pass out bibles at a food bank and it was clear to me that we were being cursed by some Satanists. So I decided to go on the offensive. I went online and I got the name of 11 Catholic priests charged with sexual crimes, and I got the name of every Free Mason in the city, and I got the name of all the Mormons in the area. I then prayed that they would repent of their sins, confess, be saved, and bring forth fruit worthy or repentance. Think what a huge blow it was to the Jewish cults during the early church when the apostle Paul was saved. The goal is to plunder Satan's kingdom. People need to be prayed over by name before they can receive salvation. Once I did that it was as though the Satanists turned tail and ran.
13 Wherefore take up the whole armor of God, that ye may be able to withstand in the evil day, and, having done all, to stand.
Do not needlessly expose yourself to Satan's attacks. They will come, you will be slandered, and accused of terrible things. If you were going to get into the ring with Mike Tyson you know you are going to get hit, so before that make sure you are completely covered with the armor of God so that you can take those hits.
14 Stand therefore, having girded your loins with truth,
First and foremost you need to know the truth. You need to be gird about with the truth. I used to be a goalie in hockey and goalies have the most extreme cup. You can get hit with a puck traveling 100 mph. If you are not properly armored up you will flinch or even crumple over, if you are then you can stare down a slap shot without fear. For example, Mike Lindell has published his testimony and in there he admits to having used crack. He shows up on a late night comedy show and the host is trying to attack him as being paranoid about the election because paranoia is a symptom of using crack cocaine. Mike responded "if that were true then you are saying every person who ever used drugs can't vote". That destroyed the comedian. Mike didn't try to lie about his past, or cover it up. You confess, you repent, then you learn the truth. Everyone is a sinner, so I don't need to let anyone condemn me, Jesus has forgiven me and paid the price. But if you try to hide or cover up those sins without confessing and dealing with them then you are not living in the truth, you are not gird about, and you will crumple up in a heap.
and having put on the breastplate of righteousness,
Jesus is our righteousness, but you have to put Him on. Mike Lindell repented for his drug use and as a result hired drug addicts trying to start again and he ran a clinic to deal with addiction. This is called fruit worthy of repentance.
15 and having shod your feet with the preparation of the gospel of peace;
I did a lot of hiking in the Southwest, spent two weeks in the hills of Nevada mapping the geology of the area. There were many rattlesnakes and scorpions. I never worried about them because I had on good boots. If you are planning to go to battle and you know there are lots of snakes and scorpions you have to have good boots. The gospel of judgment is not a good boot. Self righteousness is not a good boot. I am not here to condemn sinners, I condemn sin, but I preach the good news to sinners. I'm not trying to start a war between God and sinners, instead I am telling sinners that God has made peace with them and the good news is the price is paid, all they need to do is receive it.
16 withal taking up the shield of faith, wherewith ye shall be able to quench all the fiery darts of the evil one.
Faith comes by hearing and hearing by the word of God. You need to take up the word of God daily. Satan will be firing flaming darts, think of gossip that has the potential to go viral. Think of the nastiest, ugliest slander you can think of, doesn't have to be true, just has to have some reference to you that might be true. The more you try to put out that fire the more you just fan it into flames. That is the temptation, you want to quench it, forget it, your faith will quench it. Fill yourself up with the word, like being filled with cold water. You get hit with one of those darts it is immediately extinguished.
17 And take the helmet of salvation,
After all that you need the assurance that you are saved. When I rode a motorcycle I would wear a helmet, and when I put that helmet on it changes your attitude. When you go to battle you need to have the attitude of someone who is saved. A saved person doesn't curse others. He isn't insulting. He isn't an accuser of the brethren. Sometimes the attacks on you are true, you are a sinner saved by grace. Sometimes the best response is not to fight back but to give thanks to the Lord.
You need to make sure all of that armor is on and in place before you even consider taking up the sword.
and the sword of the Spirit, which is the word of God:
This does not mean that now for the first time you open the word of God. No, you needed to be in the word of God to be gird about with the truth. No, the sword of the spirit is sharper than any two edged sword, you want to speak a word that will divide the soul from the spirit. However, don't try that until you are fully armored up otherwise you will make some ugly cuts and reap what you sow. You will be a self righteous hypocrite. If you were a heart surgeon, the best in the country, and you tried to do a heart transplant anywhere other than the operating room you will go to prison.
18 with all prayer and supplication praying at all seasons in the Spirit,
If you take up the sword of the spirit without prayer and supplication then you will be clanging brass. This is like football, you have nine blockers and one runner. Prayer and supplication is blocking the enemy, the slander, the insults, the misunderstandings, the offenses, etc.
and watching thereunto in all perseverance and supplication for all the saints,
This is a team game, we are on a team. If you are not a team player then you should be praying that the Lord would transform you.
19 and on my behalf, that utterance may be given unto me in opening my mouth, to make known with boldness the mystery of the gospel,
Most of us are nobody, but a few of the saints are well known. If you are well known and are speaking the mystery of the gospel and making it known with boldness then you can be certain you are a critical target of the enemy. The enemy attacks all of us, but the attack will be especially brutal and well thought out when going after these ones. Think of the "Jordan rules". When Jordan played every team he played against had a special strategy and special rules in defending against him. The same is true with brothers like Paul.
20 for which I am an ambassador in chains; that in it I may speak boldly, as I ought to speak.
You want to be in chains. Many are timid to speak the word lest it cause them to be put in chains. But once you are there, what more can they do to you?
