Trials Build Character

Trials, temptations, disappointments -- all these are helps instead of hindrances, if one uses them rightly. They not only test the fibre of a character, but strengthen it. Every conquered temptation represents a new fund of moral energy. Every trial endured and weathered in the right spirit makes a soul nobler and stronger than it was before.
- James Buckham

Temptations are brought about because of Satan or ones-self. The Bible says that, "God tempteth no man but every man is tempted when he is drawn away of his own lusts and enticed." If you can overcome temptation then you will be stronger.
