In the Beginning, at Creation, God gave man Marriage and the Sabbath.

[Hobie]

We see the institution of the Sabbath given by God..

"Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made." Genesis 2:3

And marriage given by God as an unchangeable foundation for human life...

Genesis 2:24
Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.

And Christ verifies both by His own words..

Mark 2:27
And he said unto them, The sabbath was made for man, and not man for the sabbath:

Matthew 19:5
And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
