On Sunday we do special things we don't do on other days or do other special things more than what we do on other days, since other days are filled with non-sabbath things.
8 Remember the asabbath day, to keep it bholy.
Is a football game a holy activity?
Saturdayby Rita S. Robinson and Chester W. Hill Arr. Margaret C. Richards
Saturday is a special day, it’s the day we get ready for Sunday; We clean the house and we shop at the store, so we won’t have to work until Monday; We brush our clothes and we shine our shoes, and we call it our “get-the-work-done” day; Then we trim our nails and we shampoo our hair, so we can be ready for Sunday!
We must guard against individual apostasy. Recognize the deceptions of Satan to get us to leave the truth in any degree. Be on the look out of rationalizations we devise for ourselves to do wrong.
"While standards generally may totter, we of the Church are without excuse if we drift in the same manner. We have standards — sure, tested, and effective. To the extent that we observe them, we shall hinder our own progress and bring embarrassment to the work of the Lord. These standards have come from Him. Some of them may appear a little out-of-date in our society, but this does not detract from their validity nor diminish the virtue of their application. The subtle reasoning of men, no matter how clever, no matter how plausible it may sound, cannot abridge the declared wisdom of God." President Gordon B. Hinckley, "Pursue the Steady Course", Ensign, January 2005, 5.
