The Sabbathday should be kept also today. Why?
“Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But
the seventh day is the sabbath of the LORD thy God: in it thou shalt
not do any work, thou, nor thy son, nor thy daughter, thy manservant,
nor thy maidservant, nor thy cattle, nor thy stranger that is within thy
gates: For
in six days the LORD made heaven and earth, the sea, and all that in
them is , and rested the seventh day: wherefore the LORD blessed the
sabbath day, and hallowed it.” Exodus 20,8-11
“And he shall speak great words against
the most High, and shall wear out the saints of the most High, and think
to change times and laws: and they shall be given into his hand until a
time and times and the dividing of time.” Daniel 7, 25
So, which day is Sabbath?
