Whenever we discuss spiritual realities we need pratical images to explain it. In order to understand inner motivation brought about by apostolic impartation we can look to scientific evidence of combustion.
A friend explained the following to me. I mentioned it on Sunday. Perhaps we can expand the research a bit and see what we can come up with as a team?Scientific terms that help us understand the concept ?Christ within?:
Centripetal force
Centrifugal force
Endodermital action ? an action from within ? all it requires is a small catalyst to initiate the reaction that will continue from within. It becomes a natural process after the catalyst has caused the reaction. A seed that dies produces life of itself. It grows without any further support systems. It has inherent capacity to keep on growing until it reaches its full potential. If we can teach believers about Christ within they will keep on growing spiritually until they enter a state of perfection that Christ obtained after His resurrection: the Perfect Man! This is the plight of apostles and other five fold ministers: to present every man perfect in Christ!

Exoderminal action ? an action from without ? like applying constant heat to a kettle in order to make it steam continually. This refers to superficial and unnatural means to sustain an activity. Many churches have to use outside motivating forces in order to keep the believers going. The have to hype their home cell leaders up and get the audience to praise God by revving them up with loud music because the people do not have a natural capacity to worship God in spirit and truth. They rely on methods and gimmicks, systems and programs to keep the work going. Outside motivational speakers are required to draw people into the church because the growth is not inside. Thus it becomes extremely tiring and exhausting to keep the heat to the flame as it were and people get worn out, marriages break up and yet people do not grow spiritually into mature believers.
