Brother Miller.
I'll try and explain prayer as I understand it in scripture and as I've experienced it.
When it comes to the armor of God, that armor is in fact always put on daily, first thing in the morning.
But what is the armor of God? We know what Paul said as to the 'pieces' of armor we put on, but what is the actual substance of those 'pieces'?
Those pieces are as I understand them a combination of 1. The covenant promises of God, 2. the covenant commands of God, 3. our faith toward God, 4. our own experience in living under the commands of God and putting faith in the promises of God, 5. our own intimate knowledge of God through prayer, study, and teaching.
Yes, all of these things combined form our armor.
So when I wear the breast-plate of righteousness, I am wearing the covenant promise of "righteousness by faith" Rom 4. In wearing it, I learn to trust in that righteousness, given to me. In wearing it, I am tempted by Satan to take it off, or not put it on, or doubt as to its capacity to guard my heart and vitals from the sword-blows of my enemies. Since I am wearing this breast-plate I can have some assurance of safety in battle, I have confidence in what it will do for me, versus lacking such armor when in attack mode or while being attacked.
You see, that piece of armor is not only a doctrinal declaration, its a powerful aid when faith in its capabilities are experienced and victory is wrought. So, when I put on the breast-plate of righteousness, I am not simply asserting a doctrinal position, I am putting on the powerful covenant-promise capable of keeping me safe while I engage the world around me.
This same like-kind reality associates all the pieces of Gods armor to me. I know them scripturally, experientially, practically and as a living-faith-operation.
It is in this sense the authority of a believer is maximized. He goes beyond parroting a promise, he knows God's faithfulness to keep him and preserve him daily and the every-day skirmishes fit him for battles that are difficult, prolonged, lonely, and the 'seeing' of physical proof lacking.
This my brother is the norm of everyday godliness. This is the normative for those who seek to commune with God, pray for their respective families, jobs, friends and co-workers.
Intercessions teaches us that skillfulness in using the sword of the Spirit and the absolute necessity of carrying the shield of faith. Intercessions are impromptu as well as a time-given place and season for prayers; these are made in earnest to apprehend what God wants to give to us and the Church at large.
Prayer and supplication in the spirit, a kind of prayer devoted to a specific meeting ground. The meeting ground is not a building or a venue, its a 'place' where you will wrestle with Dark Princes, Powers, a genuine spiritual conflict occurs because you are dressed in the armor of God in order to persevere with 'all prayer', resisting these powers, calling upon God to reverse the influences and destruction these powers constantly inflict upon sinful humanity.
We wear our armor from the outset of the day and we never in fact take it off while we live.
Our rest, our joy and comfort is never due to a lack of conflict with the prince and powers, it is because there is not conflict between us and God.
One of Satan's chief aims for the believer is to keep him doubting and unsure about his peace with God. Satan seeks to stir up contention between us and God, fighting over God's decisions, angry because of something we suffered and another did not, or we lack something others have. If we are un-peaceful with God, walking into spiritual conflict will only intensify our God-conflict and we will be only a very short time resisting Satan.
The very point of God's armor given to us, is that we are at peace with God, Jesus Christ has perfected us, he has made us acceptable to God, and now we are indwelt by the Spirit of God. This basic truth is the foundation upon which we venture to believe God and put on the whole armor of God...and pray.
