This is a picture of my running watch. It's got some pretty fancy features. It can hold up to 50 lap times and will show me the averages and all that. Kinda neat. A new feature that I just recently discovered is the 'Power Save Mode.' Don't laugh, it's pretty cool. After a certain period of time the screen turns off and helps to save the battery. You never know when that battery is gonna die.
Each of us has a 'battery' so to speak. Our lives here on earth are bound to end some time. We just don't know when exactly. Heavenly Father has given us commandments to help us turn on the 'Power Save Mode.' These specific commandments are called the Word of Wisdom1 and were revealed to the Prophet Joseph Smith. In the Word of Wisdom we are advised not to partake of harmful substances such as alohol, tobacco, tea, and coffee. We are encouraged to eat fruits, vegetables, and grain. If we do so we will receive physical strength and also knowledge.
Although we do not know the reasons for all of God's commandments, we do know that He loves us and wants what is best for us. I know that the Word of Wisdom is revelation from God to help us today.
