Luke 4:16
And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
Acts 13:44
And the next sabbath day came almost the whole city together to hear the word of God.
Isaiah 66:23
And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
These scriptures reveal for me 1. The importance of keeping the practice of Shabbat consistent. 2. That the nations will come together again to celebrate.
