This is what happens when men try and use God's Word to justify sin, in this case, working on His Holy Sabbath. What they do is "omit" parts of the Word which bring their religion into question. For instance, to justify working on God's Sabbath, or doing whatever it is they believe needs justifying, they preach God only commanded Israelites not to steal, murder, Keep His Sanctified Sabbath Holy, etc., therefore God's Instructions are not for them.
To believe this, one must be convinced that God is a respecter of persons. They must also "omit" for their consideration the following Word's of the Christ before He became a man.
Ex. 12:
49 One law shall be to him that is homeborn, and unto the stranger that sojourneth among you.
Is. 56:
1 Thus saith the LORD, Keep ye judgment, and do justice: for my salvation
is near to come, and my righteousness to be revealed.
2 Blessed
is the man
that doeth this, and the son of man
that layeth hold on it; that keepeth the sabbath from polluting it, and keepeth his hand from doing any evil.
3 Neither let the son of the stranger, (Gentiles) that hath joined himself to the LORD, speak, saying, The LORD hath utterly separated me from his people: neither let the eunuch say, Behold, I
am a dry tree.
4 For thus saith the LORD unto the eunuchs that keep my sabbaths,
and choose the things that please me, and take hold of my covenant;
5 Even unto them will I give in mine house and within my walls a place and a name
better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off.
And "omit" the Word's of Christ after He became a Man.
Matt. 5:
17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled
Mark 2:
27 And he said unto them, The sabbath was made for man (Humans), and not man for the sabbath:
28 Therefore the Son of man is Lord also of the Sabbath.
And you must also "omit" many word's of His Apostles.
Rom. 2:
6 Who will render to every man according to his deeds:
7 To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 But unto them that are contentious,
and do not obey the truth, but obey unrighteousness, indignation and wrath,
9 Tribulation and anguish, upon
every soul of man that doeth evil, of the
Jew first,
and also of the Gentile;
10 But glory, honour, and peace, to
every man that worketh good, to the
Jew first,
and also to the Gentile:
11 For there is no respect of persons with God.
12 For as many as have sinned without law
shall also perish without law: and as many as have sinned in the law
shall be judged by the law;
13 (For not the hearers of the law
are just before God, but the doers of the law shall be justified.
Acts 5:
29 Then Peter and the
other apostles answered and said, We ought to
obey God rather than men.
So you have been convinced and you preach that God's Law is only given to Israel.
But the Christ, before He became Flesh and Blood, after He became Flesh and Blood, and His apostles after He ascended, says differently.
These Words are not speculation like you preaching God didn't give His 10 commandments to Adam, Cain, Sodom, or Abraham. But waited until Moses to give them.
Or even out and out falsehoods like your preaching that God only gave His 10 Commandments to Israel. These are all Word's inspired by the Holy God who the Man Jesus instructed we should live by.
But if we don't "Believe in Him" and His Word, then how can we "live by them". Those the Christ warned of in Matt. 7 are a testimony of what happens to folks who claim to know the Christ, but do not do as He instructs.
I also think it is wise to accept God's Definition of Good, polluting something, having Faith, what "sin" is. And when the Word shows us, we should be like David, not the Mainstream Preachers of Christ's time.
