Hard work. (Matthew 11 v 28 )

I read something amusing , as regards Sabbath keeping at the time of Jesus,'that it was hard work keeping the Sabbath'.I wonder do you appreciate the point of these words?,the Sabbath was suppose to be a day of rest,but instead it turned into a day of rule keeping.All legalism ,is hard work ,now of course there are things we should do on the Sabbath,if possible we should meet with God's  people,that's important,fellowship with Gods people as I say is important. We are part of God's family,and meeting with them, helps us and them,as we share with them, as we meet together.That meeting with them should be meaningful,to often going to meet with Gods people is an in and out experience.I was talking to a brother about a certain fellowship he knew,and said you had to attend there 20 years before you become accepted. That can't be true fellowship it is in fact a travesty ,and insult to  what fellowship should mean.Now returning to  Sabbath keeping being hard word, legalism ,whither on the  Lords day or any other day ,makes a mockery of the one who said ,' Are you  tired ?worn out? burned out in religion? Come to Me, and you will recover your life, I'll show you how to take rest' Matthew 11 v 28 ( The Message a paraphrase)
