Whenever Fridays come, the social networking sites are awash with "TGIF" posts. Notwithstanding the casual and irreverent use of God's name, the sentiment speaks of the innate longing of man for rest. While work itself is not part of the curse (work is a creational mandate), the world wherein this work is done, after the Fall, is indeed cursed and makes work not devoid of pain.
What may not be privy to many who spew this banal phrase is that the weekend heralded by it is actually founded on another creational principle: the Sabbath. The 4th Commandment was kept by the Israelites even before the Mosaic Covenant was ratified, which speaks of its enduring validity, going beyond the abrogation of the said covenant.
The following posts speak of what the Sabbath is for the worn-out pilgrim: Westminster Wednesday: Refreshment for the Weary and The Weekly Antidote to Worldliness
Whereas the unbeliever exults in the opportunity to indulge more of his autonomy over the weekend, the Christian sees this time as a privilege and blessing afforded by God for making His people have a foretaste of heaven, to which they may exclaim with true reverence and gratitude, "Thank God It's Sunday!"
