Instructively, this day is represented — surely intentionally— as having no evening/ night. God’s rest is conceptualized as having no darkness, a negative theological symbol for oppression and death. On that day the horrific primordial chaos is banished forever. In other words, by resting on the Sabbath, Israel experiences the world to come, a world of untarnished blessing that they are destined to inherit in the eschaton. Moreover, as human beings exert sovereignty over space and matter, which they build with and possess, the sanctification of time reminds them that there is something transcendent beyond matter and space. The critical moments are not the ones spent building, possessing, and controlling, but the times set apart for quiet, reflection, meditation, and worship.

Jabez was more respected than his brothers. His mother had named him Jabez, for she said, “I experienced pain when I gave birth to him.” Jabez called out to the God of Israel, “If only you would greatly bless me and expand my territory! May your hand be with me! Keep me from harm so I might not endure pain!” God answered his prayer.

 - 1 Chronicles 4:9–10, NET

In so far as we love the gospel, to that extent let us study the ancient tongues. And let us notice that without the knowledge of the languages we can scarcely preserve the Gospel. Languages are the sheath which hides the sword of the Spirit, they are the chest in which this jewel is enclosed, the goblet holding this drought.

So although the Faith and the Gospel may be proclaimed by preachers without the knowledge of languages, the preaching will be feeble and ineffective. But where the languages are studied, the proclamation will be fresh and powerful, the Scriptures will be searched, and the Faith will be constantly rediscovered through ever new words and deeds.
