i) Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
iii) For every action there is an equal and opposite reaction.
I believe these 'scientific' ideas can be applied into all areas of life....
For example, whatever you do or decide, there will be some kind of reaction or consequence. You push someone, they will fall down. You speed and you will get a letter from the cops with a nice fine. You do good things and people will appreciate you... etc. etc. Its like the analogy that if you go back in time, even if you step on a little ant, it could change the whole course of the future. Or the analogy of your life being a glass jug... and the rocks and pebbles inside are all the different parts of you and your life. If you take a bit out, add a bit in, or disturb it in any way, it will cause reactions to the rest of your life, and other people's lives too. Life isn't compartmentalised, its a conglomeration of everything you are.
Recently I've been thinking and I've listened to a couple of good talks on Romans. A good preacher, Martyn Lloyd-Jones, in one of his sermons, stated that if he could summarise Christianity in two words, he would pick 'But Now'. Why? Jesus has intervened in the course of history. He has impacted the 'uniform motion' perceived by the world and the consequence is that we have to respond to Him. Tomorrow's sermon at church is "Jesus' impact on the world". How did Jesus impact the world? Was he just another man, a good man, a prophet, or is He the King, the Messiah, the saviour of the world?
