Although many won't agree, history has shown it to be true. "When a community or nation grows careless in its Sabbath activities, its religious life decays and all aspects of life are negatively affected. The blessings associated with keeping the Sabbath day holy are lost." Sunday isn't meant for football and shopping but for worshipping God.(Exodus 20:8-11)
We rest from our usual work and activities, but part of this rest is dedicating our spirits to Christ through worship and renewing our covenants by partaking of the Sacrament. Attending church with other believers, we strengthen each other, teach each other, and bear one another's burdens.
Of course part of the sabbath is renewing by our associations with friends and family but not at the shopping mall, soccer field, movie theater, or restaurant. Participating in common recreation desecrates the Sabbath. Joy and peace are found when the Sabbath is set apart from worldly activities and dedicated to worship, repentance, thanksgiving, service, and appropriate family-centered activities. (Isaiah 58:13-14)
