Sabbathing or honoring God’s Sabbath is important and Exodus 20:8 KJV tells us that it is something God requires of us:
Remember the sabbath day, to keep it holy.
Keeping this commandment from God requires knowing what “Sabbath” is as Exodus 20:9-10 KJV continues:
 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:
Sabbathing God requires stopping everything we are doing and giving our 100% attention to Him.
The Hebrew Manuscripts show “Sabbathing” in the Lord as “Resting” in Him. “Sabbath” is “Shabath in the Hebrew language and the Hebrew Manuscripts show its use as follows:
shabath, shaw-bath'; a primitive root; to repose, i.e. desist from exertion; used in many implication relations (causative, figurative or specific) :- (cause to, let, make to) cease, celebrate, cause (make) to fail, keep (sabbath), suffer to be lacking, leave, put away (down), (make to) rest, rid, still, take away.
“Shabath” does not make reference to any particular day of the week nor is “Holy Day” shown as one of its uses. Its use does include ceasing all activities to enable us to celebrate a unique closeness to God; “Resting” and “Sabbathing” in Him attains it.
Throughout Old Testament days God strived to have us seek forgiveness and to have us love Him. Unfortunately His Commandments were ignored and misunderstood and blood sacrifices and ordinances had to be disposed of when He sacrificed His only Begotten Son.
Sabbathing God experienced a similar fate. Being celebrated as a “Holy Day”, it led God’s Children away from its original intent. This was very noticeable when while attempting to convince the Roman Governor to crucify Jesus for claiming to be the Son of God, the Priest also accused Him of not being Holy, of not honoring “Sabbath” as a “Holy Day”.
“Sabbath” was and continues to be misunderstood and Paul, in Col. 2:14-15 KJV joins us in tackling and understanding “Sabbath”:
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;  And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
