No I didnt miss it. It’s 15:21 by the way. Do you honestly think that Paul told new gentiles to go to a Jewish synagogue to learn about Jesus? The people that rejected Jesus.
Well we do not have to take what you think about the situation, the Bible tells us plainly.
Acts 13:42 So when the Jews went out of the synagogue,
the Gentiles begged that these words might be preached to them the next Sabbath. 43 Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of God.
44
On the next Sabbath almost the whole city came together to hear the word of God. 45 But when the Jews saw the multitudes, they were filled with envy; and contradicting and blaspheming, they opposed the things spoken by Paul. 46 Then Paul and Barnabas grew bold and said,
“It was necessary that the word of God should be spoken to you first; but since you reject it, and judge yourselves unworthy of everlasting life, behold, we turn to the Gentiles. 47 For so the Lord has commanded us:
‘I have set you as a light to the Gentiles,
That you should be for salvation to the ends of the earth.’ ”
48
Now when the Gentiles heard this, they were glad and glorified the word of the Lord. And as many as had been appointed to eternal life believed.
49
And the word of the Lord was being spread throughout all the region. 50 But the Jews stirred up the devout and prominent women and the chief men of the city, raised up persecution against Paul and Barnabas, and expelled them from their region. 51 But they shook off the dust from their feet against them, and came to Iconium. 5
2 And the disciples were filled with joy and with the Holy Spirit
The Sabbath is a holy convocation to worship and hear the word of God thus saith the LORD Lev23:3 Isa66:23 Isa56:6-7
Why instead of day one preaching the gospel, it was every Sabbath, because the Sabbath according to the LORD of the day to keep holy and honor God for all people.
Why we see Sabbath-keeping for God's people because it remains for the people of God.
Why we see Sabbath-keeping for many many generations in every city on every Sabbath preaching God's Word because it was established by God Himself. The enemy of God is who changed God's times and laws Dan7:25 not God, not the apostles, they were servants of God and a servant of God joins themselves to Him and keeps God's Sabbath Isa56:6
Acts 17: 2
Then Paul, as his custom was, went in to them,
and for three Sabbaths reasoned with them from the Scriptures, 3
explaining and demonstrating that the Christ had to suffer and rise again from the dead, and saying, “This Jesus whom I preach to you is the Christ.” 4 And some of them were persuaded; and a great multitude of the devout Greeks, and not a few of the leading women, joined Paul and Silas.
Acts 18:4 And he reasoned in the synagogue
every Sabbath, and persuaded
both Jews and Greeks.
With so many people claiming the Sabbath ended at the Cross or turned into Jesus there is sure a lot of Sabbath keeping hearing the gospel of Christ every Sabbath with Jews and Greeks decades and decades after the Cross. The apostles were told by Jesus to observe everything He commanded - they observed every Sabbath and not once told anyone day 1 is the day we gather. That happened outside of God's word just as predicted. Acts 20:29
The people that put them out(
John 16:2). Did Paul say, here’s four things you need to know, now go let the people that hate us teach you the rest?
If the Sabbath was 'for everyone' and the Apostles were so clear about it, why is there not one single command in the letters to the Romans, Galatians, Ephesians, or Colossians telling them to keep the seventh-day Sabbath? If it’s the 'test of the end times,' why did the New Testament writers leave it out of every single letter they wrote to the churches?
You have an interesting way of interpreting Scriptures. Can you point to the verse that each of the commandments are not repeated in every chapter that is deletes the commandments of God. Both Jews and Gentiles were keeping the Sabbath in every city already, Acts15:21 they were already keeping the Sabbath because it is a commandment of God and God's people keep God's commandments Rev14:12
We were told after Scripture that there would be a great falling away.
2 Tim 4:3 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; 4 and they will turn their ears away from the truth, and be turned aside to fables.
No wonder Jesus is calling His people out of these false teachings and back to worshipping the God of Creation Rev14:7 Exo20:11 before its too late Rev18:4
