Matthew tells the story of Christ and the disciples walking through a field (on the Sabbath) and plucking the mature heads of grain, rubbing it between their hands, blowing away the chaff and having an on-the-road snack.
Well, the Pharisees were keen-eyed observers of (other folks) of community goings and said (probably excitedly) "Look, Your disciples are doing what is not lawful to do on the Sabbath!" [Matthew 12:2].
Where do you suppose the Pharisees got the idea that eating fresh plucked grain (on Sabbath) was a sin. Let's go to Deuteronomy and check it out. "When you come into your neighbor's standing grain, you may pluck the heads with your hand, but you shall not use a sickle on your neighbor's standing grain." [Deuteronomy 23:25].
Question: Which end of the Sabbath do you enjoy most; sunset Friday or sunset Saturday? Do Adventists "keep" the Sabbath...whatever that means...or celebrate the Sabbath. There is a difference you know. To look forward to the beginning of Shabatt is to enjoy and celebrate what God has Created. To look forward (read watch the clock] to the end of the Sabbath, is to endure the time and completely miss the point. So, what is the point? More on that later. It's only Monday, but Sabbath is coming. Is that exciting or disappointing?
