In order to play a musical instrument, you must practice. By practicing you improve and gain experience. In a work environment you gain experience and knowledge by learning from those around you and being put in situations where you learn.
Life is similar – To learning how to get through life you must experience a difficult situation so that you learn from them. They then give you the strength and encouragement to know that you can face any difficult situation in the future, and you will get through it.
So even if you’re experiencing an earthquake in your life just now, be strong, and remember God is with you through it all and will help make you stronger.
