Sabbath Rest?

I am bemused by a common argument used against the observance of Sabbath; that is that ” Jesus is now my Sabbath rest” because this or that one has ceased from his own works. The insinuation is that those who do observe the Sabbath as a day of rest according to the commandment, have not ceased from their own works.
My question is this, though it seems obvious to me: how can anyone observe the day as a Sabbath, without ceasing from his/her own works?

The Ten Commandments: too tough?

Inherent in the Ten Commandments is the gospel. The first commandment has been edited by most but if we read the entire passage of scripture, we can readily see that God is not commanding us to do the impossible. The Ten Commandments begin:
Exodus 20:2 ” I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.You shall have no other gods before Me.”

In this small portion of the scripture is found the key to understanding our relationship to God’s laws, and how to find the power to obey them. Here is the gospel.
You may be thinking, “Hey, that first part isn’t a part of the law, because it doesn’t tell us something we must do or not do! Instead, it tells us of something God has done!!!”
Yes, exactly! And that’s the point. The entire Ten Commandments start with something God has done, and not with something we must do.

The Curse of the Law and the Gospel.

In Galatians 3:24 we are told that the law is a schoolmaster bringing us to Christ. Both the moral law of ten commandments and the ceremonial law do this. The ceremonial law revealed to Israel the provision made by God for their redemption, and the means by which Israel might avail themselves of that provision.
The moral law is a transcript of God’s perfect character,revealing how far we have fallen,and is the image of Christ as reflected in Adam and Eve before the fall (Gen. 1:26,27). It is God’s purpose to recreate that image in us (Rom. 8:29), but He had to deal with the effects of sin first.
One, the curse of the law. We are under the curse because of transgression. The curse is the penalty for sin. The scriptures say that Christ became a curse for us (Gal. 3:13); His death took away the penalty and the curse which was upon us because of sin, which is transgression of that law. Christ’s death enables God to impute to us His righteousness. God looks upon us now as if we had never sinned. We are now as acceptable to the Father just as Jesus Himself is. This is ‘at-one-ment’.
Two, this atonement continues by His resurrected life which enables us to receive the power necessary to keep the law in future. This is possible however only as we abide in Him, as the branch to the vine. Separated, we can by no means accomplish anything for Him and we invariably fall, “for without Me ye can do nothing” (John 15:5). Eternal life is guaranteed only as we maintain our connection to Christ through faith, for the “just shall live by faith”. The moral law is still holy just and good, (Rom.7:12) it has not been done away with in any particular (Matt. 5:17,18) but rather it has been written upon our hearts and minds (Heb. 8:10): In other words  God’s very own righteousness or character of love is developed in us by His Spirit, (for love is the fulfilling of the law) and we are recreated in Christ’s image as Adam and Eve were before the fall.
It is God’s part to accomplish this (grace) but it is our part to desire it. God will not do anything without our cooperation and agreement,for “they that hunger and thirst for righteousness will be filled” (Matt. 5:6). This takes a lifetime of warfare against the old nature, but as we continue to faithfully trust God to accomplish all He has promised, and submit wholly to Him, He will mould us and shape us like the Master Potter with the clay, and our characters may be perfected.
