And now you add false accusations to the list. Christians can't be said to keep Sunday holy as a group. There are a few who approximate your idea. Notice I said a few.
Yeah the obedient ones were always in the minority. It was always unpoular when people would say to YHWH's children that they had to get back to following the law and it's the same today. The Bible talks about the remnant being saved. I.e. a few.
Yeshua said:
Matthew 7:21-23
21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
People will call Yeshua Lord but Yeshua will say that he never knew them. This even highlights those that will enter the kingdom of heaven amongst those who call him Lord, the one's who do his father's will. The one's who follow his father's law. When it says those who work iniquity it actually should say those who break the commandments of YHWH. That is what the word mean in the original Greek.
Obedience is so important:
Acts 5:32
32 And we are his witnesses of these things; and so is also the Holy Ghost, whom God hath given to them that obey him.
Hebrews 5:9
9 And being made perfect, he became the author of eternal salvation unto all them that obey him;
1 John 5:2-3
2 By this we know that we love the children of God, when we love God, and keep his commandments.
3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
John 14:15
15 If ye love me, keep my commandments.
Revelation 12:17
17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Revelation 14:12
12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
James 1:25
25 But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
1 John 2:3-4
3 And hereby we do know that we know him, if we keep his commandments.
4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
If you say you know Yeshua but you don't follow his commandments then you are a liar. Yeshua says himself in Matthew 7:21-23 that he doesn't know many who call him Lord. It's really obvious.
Romans 8:1
8 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Romans 8:5-10
5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
6 For to be carnally minded is death; but to be spiritually minded is life and peace.
7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
8 So then they that are in the flesh cannot please God.
9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
10 And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
Romans 7:14, 22, 25
14 For we know that the law is spiritual: but I am carnal, sold under sin
22 For I delight in the law of God after the inward man:
25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
