The motor/engine of the moving vehicle has two essential and distinct, combined cycles/processes that ensure it being well tuned and running correctly for its intended purpose. These members comprise of unique parts, like members of an orchestra that brings life to the ears of those listening as the audience, from the commands of the conductor, the leader of the Body of musicians.
These two processes are the cam(shaft) timing cycle, moving the internal crankshaft, valves, pistons, rods in spaces called cylinders, in precise timing and movement, and the ignition timing cycle(s) (with 4 movements - from sucking in the air and fuel mixture to its exhaust).
They all work like a symphony of notes of moving parts or members fulfilling their functions that breathes in and consumes energy to expel its as work or movement, heat and moisture along with other byproducts.
They key and the most crucial part to its success however is the timing of the spark of ignition, or igniting the spark of life at the right time for the motor to perform in complete synchronization. If this is 'off' all the other parts and processes fail to perform as designed.
We as the Body of Christ perform like this mechanical, electrical and physical vehicle to fill ourselves with faith and the word of God and to produce fruits that please our Father. He sets this crucial timing for this 'spark of life' for his Body.
To 'play music' through preaching and instructing, and sharing our love from God, and acts of giving of oneself to strangers and brethren alike. We do it for our conductor first and foremost, our Messiah, however ultimately to please our Father, for his purpose, glory and his name.
