If you are new to Preparedness (or checking to see where you're at); Start Here with the Basics
"Our Heavenly Father created this beautiful earth, with all its abundance, for our benefit and use. His purpose is to provide for our needs as we walk in faith and obedience. He has lovingly commanded us to “prepare every needful thing” (see D&C 109:8) so that, should adversity come, we can care for ourselves and our neighbors and support bishops as they care for others.
"We encourage members world-wide to prepare for adversity in life by having a basic supply of food and water and some money in savings.
"We ask that you be wise as you store food and water and build your savings. Do not go to extremes; it is not prudent, for example, to go into debt to establish your food storage all at once. With careful planning, you can, over time, establish a home storage supply and a financial reserve."
