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 :  Which are a shadow of things to come; but the body is of Christ.
Romans 6… Shall we sin that grace may abound?…
2 Corinthians 3:3-6
 Forasmuch as ye are manifestly declared to be the epistle of Christ ministered by us, written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshy tables of the heart.  And such trust have we through Christ to God-ward:  Not that we are sufficient of ourselves to think any thing as of ourselves; but our sufficiency is of God;  Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
 And he said unto them, The sabbath was made for man, and not man for the sabbath:
 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
 For thus saith the Lord God , the Holy One of Israel; In returning and rest shall ye be saved; in quietness and in confidence shall be your strength: and ye would not.  But ye said, No; for we will flee upon horses; therefore shall ye flee: and, We will ride upon the swift; therefore shall they that pursue you be swift.
 Come unto me, all ye that labour and are heavy laden, and I will give you rest.  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.  For my yoke is easy, and my burden is light.
Sleep restores your body; rest restores your soul.
Sleep prepares you for another day of labor.
Rest prepares you for life.
 Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it.  For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it .  For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world.  For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works.  And in this place again, If they shall enter into my rest.  For if Jesus had given them rest, then would he not afterward have spoken of another day.  There remaineth therefore a rest to the people of God.  For he that is entered into his rest, he also hath ceased from his own works, as God did from his.  Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief.
See your Sabbath as Jesus….don’t let yesterday or tomorrow have your day of rest.
Must first understand the earthly/natural things before we can understand heavenly/spiritual things.
 When the people therefore saw that Jesus was not there, neither his disciples, they also took shipping, and came to Capernaum, seeking for Jesus.  And when they had found him on the other side of the sea, they said unto him, Rabbi, when camest thou hither?  Jesus answered them and said, Verily, verily, I say unto you, Ye seek me, not because ye saw the miracles, but because ye did eat of the loaves, and were filled.  Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.  Then said they unto him, What shall we do, that we might work the works of God?  Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
Hebrews 4…through rest we enter into salvation
 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
