While looking at, reading, pondering, and considering a single verse can be useful and enlightening, as often happens, taking a verse without considering its surrounding context can lead one down erroneous paths.
In particular, one must look at the full complement of armor God provides us with shown in Ephesians 6:10-18, not just part of it. How long would soldiers last in a battle with only a shield, or just a sword? God has equipped us believers to fight the spiritual battles that Satan brings our way continuously. Satan's tricks include everything from mental and emotional problems, physical ailments, family problems, and, of course, he's always trying to distract us from keeping our eyes, mind, and heart focused on our Savior, the Lord Jesus Christ. Like many Christians, I've had my share of all the above, oftentimes seemingly more than I can stand. While going through one of the 'dark valleys' of life, I frequently attempt to figure out just how can this possibly be good for me, per Romans 8:28?
Romans 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose. (KJV)
Many times, when it's over, I still wonder just HOW can that be good for me? But God knows. I can never forget the darkest days of my life after I left my wife 28 years ago. Had that not happened, I would never have moved 1000 miles away for a job and been saved 5 years later! Gods' plan and timing is always perfect! HE is in control!
In looking at the full description of our battles and armor described by Paul in Ephesians, there's several things that immediately 'pop out'. First and foremost, our battles are spiritual, not physical. Although Satan may attack our health or the health of those close to us, or put our house in the path of a forest fire, it's important to simply 'give it all to Jesus'. THAT has been a long hard slog for me to learn...the hard way, of course. Since February 2021, I've had a couple of seemingly impossible financial problems befall me. I struggled with each of them trying to figure out a solution before I finally realized: "God, there's no way out of this in my own power, I have no choice but to leave it all to You to solve." Of course, He did!
Part of my struggles stem from forgetting one of the first verses I memorized after I was saved:
Matthew 6:33 But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. (KJV) (underlining mine)
The other big thing that jumps out is that all the armor is for offense and is on our front side. Our weapons are the sword (His Word) and prayer. We don't have anything on our backside for defense, so we cannot retreat. We don't have a shield on our backside, etc. So we are to use the weapons He has provided us to be victorious -
Ephesians 6:10-18 (KJV)
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.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
Using all of our armor rather than some of it is the way to victory against Satan.
