If you refrain from trampling the sabbath,
from pursuing your own interests on my holy day; if you call the sabbath a delight
and the holy day of the Lord honourable; if you honour it, not going your own ways,
serving your own interests, or pursuing your own affairs; then you shall take delight in the Lord,
and I will make you ride upon the heights of the earth; I will feed you with the heritage of your ancestor Jacob,
for the mouth of the Lord has spoken.Isaiah 58.13-14
"When religious rituals like sabbath-keeping and fasting — or our Bible studies, sermons, church attendance, and retreats — are divorced from human health and wholeness, whenever a believer "turns away from your own flesh and blood" (Is. 58:7), then our religion has gone very bad indeed."
