thank you for your postTo me, the importance is not in which day it is kept, but in that we set aside a day for God and for rest. Don't misunderstand me, as every day should be spent with God and he should be first in all things. But I believe that the act of having a Sabbath is the act of setting side one day to honor and glorify him and all the he is and has done. The importance is not in a legalistic act of counting minutes or selecting a day. The importance is in the meaning behind the setting aside of a day and in what we do on that day. If we allow ourselves to get so caught up in laws and legalism, then we miss the beauty beyond those things.
Just my thoughts... I know I did not explain it well.
