About Sabbath

What is the Sabbath?
The first mention of the seventh day, and it being made holy by God, is in Genesis, when creation was completed:
"By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work.  Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done." - Genesis 2:2-3
Sabbath is asked to be observed in the fourth of the 10 commandments:
“Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy." - Exodus 20:8-11
Jesus gives some good insights to Sabbath activities in Matthew 12:
At that time Jesus went through the grainfields on the Sabbath. His disciples were hungry and began to pick some heads of grain and eat them. When the Pharisees saw this, they said to him, “Look! Your disciples are doing what is unlawful on the Sabbath.”
He answered, “Haven’t you read what David did when he and his companions were hungry? He entered the house of God, and he and his companions ate the consecrated bread—which was not lawful for them to do, but only for the priests. Or haven’t you read in the Law that the priests on Sabbath duty in the temple desecrate the Sabbath and yet are innocent? I tell you that something greater than the temple is here. If you had known what these words mean, ‘I desire mercy, not sacrifice, you would not have condemned the innocent. For the Son of Man is Lord of the Sabbath.”
Going on from that place, he went into their synagogue, and a man with a shriveled hand was there. Looking for a reason to bring charges against Jesus, they asked him, “Is it lawful to heal on the Sabbath?”
He said to them, “If any of you has a sheep and it falls into a pit on the Sabbath, will you not take hold of it and lift it out? How much more valuable is a person than a sheep! Therefore it is lawful to do good on the Sabbath.” - Matthew 12:1-12

 And Mark 2 adds:
Then he said to them, “The Sabbath was made for man, not man for the Sabbath. So the Son of Man is Lord even of the Sabbath.” - Mark 2:27-28
There's much more that could be studied about the Sabbath. We'll add to this section later - but for now we'll stick to what we do best - inventing new was to enjoy the Sabbath!
