The Perfect Sabbath Is In God's Place Of Rest.

This is what sabbath means for those who are in Christ. Those who want to still follow the sabbath as it was written in the law of Moses are cheating themselves and/or are living in ignorance. Let look at what our Lord revealed through the Apostles.

Hebrews 4:3-10

New International Version (NIV)

3 Now we who have believed enter that rest, just as God has said,

“So I declared on oath in my anger,
‘They shall never enter my rest.’”

And yet his works have been finished since the creation of the world. 4 For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works.” 5 And again in the passage above he says, “They shall never enter my rest.”

6 Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience, 7 God again set a certain day, calling it “Today.” This he did when a long time later he spoke through David, as in the passage already quoted:

“Today, if you hear his voice,
do not harden your hearts.”

8 For if Joshua had given them rest, God would not have spoken later about another day. 9 There remains, then, a Sabbath-rest for the people of God; 10 for anyone who enters God’s rest also rests from their works, just as God did from his.

Explanation
There is a "place of rest" in God and a "day of rest(ie Sabbath day)." these are two different things. Sabbath=rest form works and Sabbath day is the day of that rest.

Joshua did not lead the people into that into that place of rest v8 even as they rest every Sabbath day. Another day was spoken of which is "Today" if you listen to His voice.

In v3, you will see that God is now resting since He finished His works long ago. Those who enter that place of rest where our God is having His rest are those who have believe/exercised faith v3. So there is a Sabbath resting for the people of God, If you enter God's rest you are observing your Sabbath, v9,10. You can enter that rest today by exercising faith in Christ, through him you will go to the Father and rest with Him.

Therefore those who pride themselves in saying that they changed the sabbath day and it was acceptable by the whole world are doing so in ignorance. The same goes to those insisting that the sabbath day must be saturday. The Lord of the sabbath(Jesus) has given us a perfect sabbath and so it is for those who enter God's rest.

Those who tell you that you have sinned for not going to church on sunday or a sabbath day are just ignorant. this is what the Truth has given his followers:
Colossians 2:16
King James Bible (Cambridge Ed.)
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:

The word of God is what made the church the pillar and foundation of truth, 1Tim 2:15. You can choose any day to fellowship with the brethren but you enter God's rest any day any time.

Na wa for those believing church fathers doctrine. Are these things not clear or what? How can a set of people be so deluded?
