LOL.
It is more directed to the combustion chamber. The pressure builds as the flame front starts across the chamber, but if the chamber is incorrectly designed a trapped section self detonates causing a destructive knock (stealing hp and damaging parts).
If we are saved as through fire, every area of our life is ignited to burn off impurities. We do not explode from pressure. Pollution is caused by detonation.
David being informed of thou art the man, makes him aware of taking Bathsheba. Fire slots in head design can take ignition flame to dark areas of a combustion chamber and cause a burn rather than an explosion. Explosions emit unburned fuel (pollution).
Even diesels are beginning to not have the pronounced knock.
I John 1:7
But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
An illumination occurs as a fuel burns. Extra oxygen burns off the dross. Our life is helped when we do not emit unburned emotional particles. Getting things (sins / falling short) into the light helps.
This discussion is not for everyone. I have to work on all this myself.
