What is the sabbath? Is it even importnat to know? Can't I just love Jesus and try to be good and that's enough?
These are important questions. Let's look at the first.
"I was in the Spirit on the Lord's day, and heard behind me a great voice, as of a trumpet," Revelation 1:10
The bible teaches that the Lord has a day. Who is the Lord? Jesus Christ. Which day is His day?
"And he said unto them, The sabbath was made for man, and not man for the sabbath: Therefore the Son of man is Lord also of the sabbath." Mark 2:27,28
"If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:" Isaiah 58:13
The Sabbath was made or Instituted for man and not man for the sabbath. This suggests that the day is not one of bordem but where man finds happiness in His Lord and Saviour Jesus Christ who is also Lord of the Sabbath. In fact we are called to delight in the Sabbath. Not doing our own works but finding pleasure in the Lord.
This is impossible unless I understand the real purpose or reason for the sabbath. God has a day it is the Sabbath. Jesus is the Lord of the Sabbath and He made it for man to delight in quality time with Him. But thich day is the Sabbath?
"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
