Naomi@ God did not create cancer, nor any of the diseases we have. It is all the result of man's rebellion back in the Garden of Eden. Had Adam not rebelled against the direction given by God, then we would not be here today suffering from disease, old age, famines, wars, etc. etc.
As to using scripture, as a Christian I consider the Bible as the "Guide book to life". Many of the principles set out do help us in our day to day lives.
For example, in the Book of Proverbs 3 v 27-31
Do not withhold good from those to whom it is due,
when it is in your power to act.
28 Do not say to your neighbor,
“Come back tomorrow and I’ll give it to you”—
when you already have it with you.
29 Do not plot harm against your neighbor,
who lives trustfully near you.
30 Do not accuse anyone for no reason—
when they have done you no harm.
31 Do not envy the violent
or choose any of their ways.
Do not withhold good from those who deserve it when it is in your power to act. The NT contains many exhortations to kindness, charity, and hospitality.
Do not say to your neighbour "come back later I'll give it tomorrow".This counsels the speedy fulfillment of one's obligations.
Do not plot harm against your neighbour: The verb "kharash" means "to cut in; to engrave; to plough; to devise." The idea of plotting is metaphorical for working, practicing or fabricating.
Do not accuse a man for no reason: The word most reasonably signifies a legal accusation, a formal complaint before witnesses and authorities.
Do not envy a violent man or choose any of his ways: Envy may carry the connotation of "imitating" as well. The word "violent" refers to physical violence, social injustice, harsh treatment, wild ruthlessness, injurious words, hatred, and general rudeness.
This is just an example, there are many many more.
