Our calendar follows a number of cycles which are based on astronomical patterns:
• Day The time it takes for the Earth to revolve on its axis.
• Month Approximately the time it takes for the Moon to orbit around the Earth.
• Year The time it take for the Earth to orbit around the Sun.
However, our calendar also follows the seven-day week, which does not match any astronomical cycle.
THE ORIGIN OF THE SEVEN-DAY WEEK AND THE SABBATH
The Bible tells us our seven-day week came from the beginning of time when God created this world. It says:
“For in six days the Lord made the heavens, the earth, the sea, and everything in them; but on the seventh day he rested. That is why the Lord blessed the Sabbath day and set it apart as holy.” Exodus 20:11
God finished the Creation week by resting on the Sabbath:
“So the creation of the heavens and the earth and everything in them was completed. On the seventh day God had finished his work of creation, so he rested from all his work. And God blessed the seventh day and declared it holy, because it was the day when he rested from all his work of creation.” Genesis 2:1-3
He then invites us to join Him in keeping the Sabbath as a day of rest:
‘Remember to observe the Sabbath, keeping it Holy.’ Exodus 20.8
God desires to spend time with us every week because He loves us. He has special blessings He wants to give to us during the Sabbath. God is inviting us to enter His divine rest on the Sabbath—the day that He has chosen.
