Prayers regarding our ... sins should be of two types. First, we should pray over them in a planned, consistent manner, probably in our ... private time with God. Second, we should pray short, spontaneous prayers for the help of the Holy Spirit each time we encounter situations that might trigger one of our sins.

Annealing A Sword
(What an awsome parrallel this is to the biblical process of conversion.)
Annealing (metallurgy) -- a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness. Annealing is used to soften material, relieve internal stresses, refine the structure by making it homogeneous, and improve properties.
Annealing occurs by the realgnment of atoms within a solid material, so that the material progresses towards its equilibrium state. Heat is needed to increase the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and destroying the dislocations in metal. The amount of process-initiating in a deformed metal is also reduced by the annealing process. In practice, this reduction of Gibbs free energy is termed "stress relief".
The relief of internal stresses is a thermodynamically spontaneous process; however, at room temperatures, it is a very slow process. The high temperatures at which the annealing process occurs serve to accelerate this process.
Mechanical properties, such as hardness and ductility, change as dislocations are eliminated and the metal's crystal lattice is altered. On heating at specific temperature and cooling it is possible to bring the atom at the right lattice site and new grain growth can improve the mechanical properties.
The purpose of annealing may involve one or more of the following aims:
1. To soften the steel and to improve machinability.
2. To relieve internal stresses induced by some previous treatment (rolling, forging,uneven cooling).
3. To remove coarseness of grain.
-
The treatment consists of:
a. heating the steel to a certain temperature,
b. "soaking" at this temperature for a time sufficient to allow the necessary changes to occur,
c. cooling at a predetermined rate.
Stages of Annealing
There are several stages in the annealing process, with the first being the phase which results in softening of the metal through removal of defects and the internal stresses which they cause. Recovery phase covers all annealing phenomena that occur before the appearance of new strain-free grains. The second phase is where new strain-free grains nucleate and grow to replace those deformed by internal stresses. A third phase, which is typically confined to hardenable steel, is used to refine grains which have been deformed through internal stress and can improve ductility and toughness of the steel. It involves heating the steel to just above its upper critical point. It is soaked at this heat for a period of time then allowed to cool in air. Small grains are formed which give a much harder and tougher metal. Ductility is important in shaping and creating a more refined piece of work. In this phase the piece is heated to a temperature typically below the annealing temperature and held there for long enough to relieve stresses in the metal. The piece is finally cooled slowly in to room temperature. It is then ready again for additional cold working. This can also be used to ensure there is reduced risk of distortion of the work piece.
Full Anneal and Normalising Treatments
For steel treatment consists in heating to about 25-50°C above the upper critical point of Fe-Fe3C equilibrium. These temperatures allow for the effects of slight variations in the impurities present and also the thermal lag associated with the critical changes. After soaking at the temperature for a time dependent on the thickness of the article, the steel is very slowly cooled. This treatment is known as full annealing, and is used for removing strains from forgings and castings, improving machinability and also when softening and refinement of structure are both required.
Normalising differs from the full annealing in that the metal is allowed to cool in still air. The structure and properties produced, however, varying with the thickness of metal treated. The tensile strength, yield point, reduction of area and impact value are higher than the figures obtained by annealing.

Philippians 3:2-11 [MSG] & [NIV]
Philippians 3:2-11 (The Message)
2-6Steer clear of the barking dogs, those religious busybodies, all bark and no bite. All they're interested in is appearances knife-happy circumcisers, I call them. The real believers are the ones the Spirit of God leads to work away at this ministry, filling the air with Christ's praise as we do it. We couldn't carry this off by our own efforts, and we know it even though we can list what many might think are impressive credentials. You know my pedigree: a legitimate birth, circumcised on the eighth day; an Israelite from the elite tribe of Benjamin; a strict and devout adherent to God's law; a fiery defender of the purity of my religion, even to the point of persecuting the church; a meticulous observer of everything set down in God's law Book.
7-9The very credentials these people are waving around as something special, I'm tearing up and throwing out with the trash along with everything else I used to take credit for. And why? Because of Christ. Yes, all the things I once thought were so important are gone from my life. Compared to the high privilege of knowing Christ Jesus as my Master, firsthand, everything I once thought I had going for me is insignificant dog dung. I've dumped it all in the trash so that I could embrace Christ and be embraced by him. I didn't want some petty, inferior brand of righteousness that comes from keeping a list of rules when I could get the robust kind that comes from trusting Christ God's righteousness.
10-11I gave up all that inferior stuff so I could know Christ personally, experience his resurrection power, be a partner in his suffering, and go all the way with him to death itself. If there was any way to get in on the resurrection from the dead, I wanted to do it.
Philippians 3:2-11 (New International Version)
2Watch out for those dogs, those men who do evil, those mutilators of the flesh. 3For it is we who are the circumcision, we who worship by the Spirit of God, who glory in Christ Jesus, and who put no confidence in the flesh 4though I myself have reasons for such confidence. If anyone else thinks he has reasons to put confidence in the flesh, I have more: 5circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; 6as for zeal, persecuting the church; as for legalistic righteousness, faultless.
7But whatever was to my profit I now consider loss for the sake of Christ. 8What is more, I consider everything a loss compared to the surpassing greatness of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them rubbish, that I may gain Christ 9and be found in him, not having a righteousness of my own that comes from the law, but that which is through faith in Christ the righteousness that comes from God and is by faith. 10I want to know Christ and the power of his resurrection and the fellowship of sharing in his sufferings, becoming like him in his death, 11and so, somehow, to attain to the resurrection from the dead.

Woe To The Obstinate !
"Woe to the obstinate children," declares the LORD, "to those who carry out plans that are not mine, forming an alliance, but not by my Spirit, heaping sin upon sin! Isaiah 30:1
