I just bought this book and, since I put my armor on each morning, I was interested and found it a value tool for any believer.  He calls it his answer book and it certainly fulfills that title.  It is a small book in size but very well done and can help you in your personal spiritual pursuit.
The more I read this book the more I believe every believer should get a copy and practice its truths.

I have added my personal material notes:

This pursuit started when I read  in 2009 the 3 volume set by William Gurnall [approximately 1000 pages] The Christian in Complete Armour begun in 1655 the result was my sermon “Independance Day” [a copy is available on request to this web site]
Here is my article “Putting on your Armor ‘Quickly'” revised.

Belt: Lord, help me to be prepared and committed to put the belt of biblical truth and read in my daily devotions so that can as a believer claim this truth during temptation [Ephesian 6:14].

Breastplate:  Lord help me by your Holy Spirit’s power and prayer help  who[Eph 3:14-21; Romans 8:26] because when Jesus died for my sins he became sin for me so that I might be made the righteousness of God [2 Cor 5:21] so that I can put off this temptation and do what is right.

Shoes: Lord may your peace made available because Christ died for my sins help me to be confident and calm so that I an overcome whatever circumstance I face on my path of life today [Eph 6:14-15].

Shield:  Lord today I claim your shield of faith to be protected from Satan’s flaming missiles aimed to tempt me to sin [Ps. 18:30].

Helmet:  Jesus died for my sinful thoughts sent to defeat, discourage and tempt me. Lord, help me to focus my mind on  the thoughts of Phil. 4:8  to protection on wisdom of God. [Proverbs 2:10-11].

Sword:  Lord, help me to hide your word in my heart and use it as Jesus did when tempted in the wilderness [Eph. 6:17; Matt. 4].

Personal Note.  At this point in my prayer I have chosen to use my Peace sermon every morning with the acrostic P -Protection, E -Entrance into Holy Spirit prayer help, Rom 8:26], A-Accepted in the beloved [Eph 1:6], C – contentment in all circumstances [Phil.4:12] and E- exalted position of 33 things received at Salvation [a bookmark and explanation is available].

My foundational premise of all my ministry is “the Christian way of life is impossible to live.  Many have tried in the flesh to live the CWL and all have failed.  Only those those who seek the aid of the Holy Spirit can live it”
