The biblical Sabbath is like a spiritual bridge that spans the ages—the past to the present and then on into the future. The seventh day Sabbath not only connects man to all three, but carries man back to the Creator and forward with him into eternity, that is, into the eternal Sabbath of the New Heavens and New Earth in the New Jerusalem. The Sabbath is a major bridge linking man to his past, present and future.
When men cease to “remember the Sabbath to keep it holy/kadoash/set-apart [from secular activities]” (Exod 20:8) and substitute it for other days of worship (e.g. Sunday) or replace it with secular work and activities, humans, to one degree or another, cut themselves off from that spiritual bridge linking them to the eternity beyond both past and future in which Elohim inhabits.
Interestingly, the Sabbath was the first biblical truth that the post-apostolic apostate-bound Christian church fathers abandoned in the second century. At the same time, the Sabbath is the first thing to which modern mainstream Christian who are rediscovering their Hebraic roots will return.
As such, these modern day spiritual truth-seekers and pilgrims are unwittingly retracing their steps back to the future and back to the point where their second century antecedents jumped off the spiritual bridge that links them to eternity and beyond.
Yeshua the Messiah is the Creator of and LORD of the Sabbath and, when on earth as a human, he never sinned by violating a single Bible commandment including the command to keep the Sabbath holy.
Moreover, the Sabbath was a sign that the Word of Elohim (who later revealed himself in flesh form as Yeshua the Messiah) audibly gave to the children of Israel at Mount Sinai as a sign linking them to himself in a deep, mystical spiritual way.
The Sabbath as a commandment and a sign linking Elohim to his people has never gone away. Yeshua is the same yesterday, today and forever and does not change.
Those who love Yeshua the Messiah will be imitating him (1 Cor 11:1) and showing him their love by keeping his commandments (John 14:15). The Sabbath will link them to him in a deeper spiritual and mystical way that only those who “remember the Sabbath to keep it holy” can fully understand.
