Since keeping the Sabbath is one of the ten commandments, do we need to keep the Sabbath as Christians today?

1)The Sabbath in Exodus- in Exodus the Sabbath was a command to rest from work (and in order to love your servants- have them rest) and to worship. It was a sign that Israel was created by and redeemed by God.

2)The Sabbath in Christ- the Sabbath is a shadow- Christ is the substance. It pointed to him- to the need for rest in him. It pointed to the fact that he would bring us into the rest of our salvation- both now and fully in eternity. This in turn frees us and enables to use this command as wisdom- to take the principle that we need rest and that it should be a part of the rhythm of our lives.
