My family and I rest and worship on the 7th day instead of Sunday. Why?
The reason is, it's one of the 10 commandments.
Exodus 20:8-11
(8) Remember the Sabbath day, to keep it holy.
(9) Six days shalt thou labor, and do all thy work:
(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:
(11) For in 6 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.
We believe that we are to keep the 10 commandments and that they are all important. ( Matthew 5:18 -19)We do not feel that any are unnecessary, or that any do not apply to us to day. We keep God's commandments out of love for God. ( John 14:15, 14:21, John 15:10) The commandments are not to be a burden but a joy!! ( 1 John 5:3 ) To me its a total love thing! ( 1 John 5: 2 , 2 John 6)
There is many places in the Bible that God has instructed us to keep the Sabbath day and one can look those up in a concordance, but I will share just a couple more verses here. Though I feel we only need the one place in the 10 commandments, for us to know this is what God wants. Another good thing to look in the concordance would be the commandments.
Genesis 2 : 1-3 , Hebrews 4: 1-11
I feel Sabbath is just one of those many things we do out of love for God, not a ticket to heaven as some may see it, nor something in order to be saved, but because we are saved and we love God, and we want to obey God. And because we want to please Him in every part of our lives.
Love and obedience go hand in hand, and I believe there is not true love if there is not true obedience.
