God gave it as a day of rest. I rest in Jesus Christ every day. Where is the problem???
That is great that you rest in Jesus every day.
When God said to Adam you may eat of every tree but not to eat the one tree that caused death. They ate the one that God said not to eat and it resulted in death. obediance was important.
God set aside the sabbath and made it holy.. Gen 2:3 And
God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made.
It is different to the other days. sanctified means set aside for holy use.
Exo 20:8
Remember the sabbath day, to keep it holy.
Exo 20:9 Six days shalt thou labour, and do all thy work:
Exo 20:10 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:
Exo 20:11 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.
If you treat the Sabbath the same as any other day and forget the commandment above you are not obeying Him, and that is disobedience.
