Again, it is only the letter that Jesus violated on the sabbath day by doing work on that day.
He did not violate the spirit of what the law is all about; because He re-defined the sabbath day law according to the spirit; so that the sabbath was made for man and not man for the sabbath; and it is lawful to do well on sabbath days; because Jesus is the Lord of the sabbath.
Our obedience to the law is not about keeping the letter perfectly (Romans 7:6); and neither was this the case with the Lord.
In fact, Jesus healed on the sabbath day to set the example that where two laws collide, the greater of two goods or the lesser of two evils is to be chosen. For Jesus, in healing a man on the sabbath, was being obedient to the command to "love thy neighbor as thyself" even though He basically violated the letter of what it says in Exodus 20:10--that thou shalt not do "any" work on the sabbath days.
Love is the fulfilling of the law. If you love someone in a practical manner on the sabbath day and this means work, you are being obedient to the spirit of the law even though you would be violating the letter.
Under the New Covenant, it is not the letter that matters any more; it is the spirit (Romans 7:6, 2 Corinthians 3:6).
I don't recall the "letter" stating you couldn't help someone though. It says no work. I understand work as a means to make an income or a profit.
And also I believe it was the LEvitical Priesthood that were to keep the candles burning continually even on the sabbath.
Lev 24:1 And the LORD spake unto Moses, saying,
Lev 24:2 Command the children of Israel, that they bring unto thee pure oil olive beaten for the light, to cause the lamps to burn continually.
Lev 24:3 Without the vail of the testimony, in the tabernacle of the congregation, shall Aaron order it from the evening unto the morning before the LORD continually:
it shall be a statute for ever in your generations.
Lev 24:4 He shall order the lamps upon the pure candlestick before the LORD continually.
Lev 24:5 And thou shalt take fine flour, and bake twelve cakes thereof: two tenth deals shall be in one cake.
Lev 24:6 And thou shalt set them in two rows, six on a row, upon the pure table before the LORD.
Lev 24:7 And thou shalt put pure frankincense upon
each row, that it may be on the bread for a memorial,
even an offering made by fire unto the LORD.
Lev 24:8 Every sabbath he shall set it in order before the LORD continually, being taken from the children of Israel by an everlasting covenant.
Lev 24:9 And it shall be Aaron's and his sons'; and they shall eat it in the holy place: for it
is most holy unto him of the offerings of the LORD made by fire by a perpetual statute.
Psa 110:4 The LORD hath sworn, and will not repent, Thou
art a priest for ever after the order of Melchizedek.
Heb 3:1 Wherefore, holy brethren, partakers of the heavenly calling, consider the Apostle and High Priest of our profession, Christ Jesus;
Heb 3:2 Who was faithful to him that appointed him, as also Moses
was faithful in all his house.
Heb 3:3 For this
man was counted worthy of more glory than Moses, inasmuch as he who hath builded the house hath more honour than the house.
Heb 3:4 For every house is builded by some
man; but he that built all things
is God.
Heb 3:5 And Moses verily
was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after;
Heb 3:6 But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.
Mat 12:6 But I say unto you, That in this place is
one greater than the temple.
Mat 12:7 But if ye had known what
this meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless.
Mat 12:8 For the Son of man is Lord even of the sabbath day.
