Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light.”
In the Old Testament they could not have the Spirit like the New Testament for their sins were not completely taken away so they were not a clean vessel.
But the blood of animals covered their sins but there was a remembrance of their sins every year which their sins had to be covered again.
So in the Old Testament they could not have peace that passes all understanding, joy that no person takes away from you, and spiritual rest, the benefits of having the Spirit.
Also in the New Testament it is a spiritual sabbath by the Spirit.
Isaiah 28:10 For precept must be upon precept, precept upon precept; line upon line, line upon line; here a little, and there a little:
Isaiah 28:11 For with stammering lips and another tongue will he speak to this people.
Isaiah 28:12 To whom he said, This is the rest wherewith ye may cause the weary to rest; and this is the refreshing: yet they would not hear.
Matthew 11:28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.
29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.
30 For my yoke is easy, and my burden is light.
Colossians 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
17 Which are a shadow of things to come; but the body is of Christ.
Jesus took the physical ordinances of Israel out of the way nailing them to His cross for they were contrary to us for they had no bearing on salvation.
And was a shadow of things to come.
So let no person judge you concerning the physical ordinances including the physical Sabbath days.
Some people say keep the physical sabbath but it is a spiritual sabbath and they will not hear.
The physical ordinances and physical laws do not mean anything in the New Testament.
Love is the fulfilling of the law which no person can obtain that without the Spirit guiding them.
That is why Jesus said He gives us rest for in the New Testament that rest is available by the Spirit where in the New Testament it was not being a physical covenant.
