I would really like to discuss the topic: What is Whole Armor of God in details, which is clear and understandable.
First lets consider the bible verses that talks about the Whole Armor of God in the Book of Ephesians chapter 6 from verse 11 to 18
11 Put on the whole armor of God, that you may be able to stand against the schemes of the devil.
12 For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.
13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm.
14 Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness,
15 and, as shoes for your feet, having put on the readiness given by the gospel of peace.
16 In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one;
17 and take the helmet of salvation, and the sword of the Spirit, which is the word of God,
18 praying at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints,
We human by nature are weak against the evil power of Satan, who tries to defeat us in our path to follow God. So as an army who prepares to go for a battle gets ready wearing his armor to protect himself as well to fight the enemies . Therefore in the same way the believers or followers of Christ are required to put on the spiritual armors to protect as well to fight the spiritual battle. This armor gives us the strength, and the ability to stand firm in our path. This spiritual armor are indeed spiritual or abstract, but yes it comes with an act of performing which is an action like truth which comes when we speak (there will be no truth until we speak it), righteousness comes when we act in just and honest way; it is not merely a thought bur rather it is a deed that we do. And, as shoes for your feet, having put on the readiness given by the gospel of peace clearly shows that Gospel is not a call to rest, rather it means not only knowing the Gospel of peace but also spreading it as by spreading peace or good news we defeat the attempt of devil who prevent truth or joy of light to be shown to others, as where there is light, there can’t be darkness which is of Satan (Rom 10:15 And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!”). By faith in God we ruin the plan of devil trying to weakness our desire to obey and follow God as we know Satan gives us too much of reasoning that we eventual forget that: faith means being sure of what we hope for and certain of what we do not see. Faith conquers him (1Pe 5:9), and his darts of temptation to wrath, lust, revenge, despair. It overcomes the world (1Jo 5:4), and so the prince of the world (1Jo 5:18). So faith, the faith that fully trusts in God and never doubts, is the best of all defenses. It will quench, stop, put out all the doubts, whisperings and evil suggestions of the wicked. We know that we have the helmet of salvation which is Jesus Christ and His words as the sword of Spirit to overcome the cunning tactics of evil one. No one can wield the sword of the spirit rightly without constant prayer and our supplication are not to be for ourself only, but for all the people of God. Also we know that praying is the most important armor as it keep us under the shelter and protection of God. This things act as the full spiritual armor of God. If Christ’s righteousness is over our hearts, we can hardly suffer harm. We see that these enemies are put to flight only with the armor of God, that is, with uprightness of conscience, a godly and holy life, knowledge of the Gospel, faith, and to be short, with the word of God. And that daily earnest prayer
The will to do good comes when the spirit of God is in us, which means Christ in us. Also God gives us grace only when we are humble. It is by grace that we receive the Holy Spirit, but again as God has given us the free will of choice; it completely depend on us as we accept it or not. The Christ in me acts when I have the desire to obey the Spirit of God. Abiding in Christ means remaining in the will and love of Christ, thereby following His steps and since Christ is perfect and He is the truth, we need to follow it with our actions as he lived and did things in perfection. God gives me grace when I do something and it is not like I am sitting down as a sinner with all burdens and all of sudden God’s grace fell on me and the spirit of Christ came in me but rather I need to be humble and repent for my sins as well I should have the desire to receive this gift. The battle with the devil was won on the cross but it was a battle in which God was making a way for our redemption, it was won once and it is for all and forever. But the battle within me with the devil continues in my quest to follow Christ till I am alive on this earth so I need to put on the whole armor of God.
This is my perception of the whole armor of God. I welcome any comments and suggestion to enhance my understanding.
