... the Sabbath as THE Day to worship God now!
Mankind is to worship God at all times, in every day. This is not the issue. The issue is the specificity of the 4th Commandment itself. To work on the other six common days, in accordance with God's word, is to worship God. To cease from all common work, upon the 7th day the Sabbath and to keep it holy, as according to God's word, is to worship God. To attempt to not so rest upon the 7th day, and to not keep it holy, by doing whatever pleases you or other men, rather than God, is to not worship God, but yourself, and thus satan.
A Christian, as the Jews did, may meet together, pray together, study together, worship together any and all days of the week. That is not the issue. The issue is in the specificity of the 4th Commandment. In fact, I meet with others regularly throughout the week to study, pray, etc, sometimes at a church buliding, sometimes in a home, sometimes out in nature.
So, indeed, and worship God every day, meet together often!, not only in Acts, yes even in the Gospels and elsewhere, the Christians [even as did the Jews] met daily, none of which eliminates obedience to God in His 4th Commandment:
Jesus met in the temple
"daily" [and not only there, also synagogue, and in nature], even especially in his last week from Sunday to Tuesday, especially: John 11:55, 21:1; Matthew 26:55; Mark 14:49; Luke 19:47, 22:53; John 18:20; see additionally [in this order, read carefully], Matthew 21:10; Mark 11:11; John 12:12,13; Matthew 21:12,13,17; Mark 11:12,15,16,17,19; Matthew 26:2; Mark 14:1; Matthew 21:18,23; Mark 11:20,27; Matthew 23:37,38,39 [Parallel to Luke 13:31,32,33,34,35]
Acts 2:46 KJB - And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,
Acts 5:42 KJB - And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ.
And does any know why this
"daily"? Understand this text -
Psalms 77:13
Also, Jesus met with the Disciples
the 2nd day of the week here, since he spent a great deal of time with the two Disciples on the Road to Emmaus on the first day [see Luke 24:21, "...beside all this,
to day is the third day since these things were done"],
it came to be evening [which begins the next day, when the sun sets at even, Mark 1:32; Leviticus 23:32; Genesis 1:5,8,13,19,23,31, etc ], and then they sat down to dinner, and as Jesus vanished before them, they ran back to Jerusalem at night and then Jesus met with them again, all together [thus no longer the 'first [day] of the week', but rather the second [day] of the week]:
Luke 24:29 KJB - But they constrained him, saying, Abide with us: for it is toward evening, and the day is far spent. And he went in to tarry with them.
Luke 24:30 KJB - And it came to pass, as he sat at meat with them, he took bread, and blessed it, and brake, and gave to them.
Luke 24:33 KJB - And they rose up the same hour, and returned to Jerusalem, and found the eleven gathered together, and them that were with them,
Luke 24:36 KJB - And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace be unto you.
Jesus also stayed for 40 days after His resurrection, His first ascension and return:
Acts 1:3 KJB - To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
Thus, since Jesus ascended for the Second time, this time from the Mount of Olives, he was there with them exactly 10 days before Pentecost [first [day] of the week], which means, we see again that Jesus was with them not merely upon the first [day] of the week.
Hebrews 10:25 KJB - Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching.
The "the day" is two things:
[1] the 7th Day the sabbath of the LORD [Jesus] thy God, at the culmination of each week, an "holy convocation" [Leviticus 23:3; Exodus 20:8; 2 Peter 2:21 KJB]
[2] the Day of the LORD, the great cosmic Sabbath, the second Advent, unto the third advent, known as the 1,000 years, which will begin here [the evening portion, the dark part, when no man can work, probation closed, and in Heaven there is no night there] on earth, soon, this being the greater 7th Day with the LORD, as per Psalms 90:4; 2 Peter 3:8, etc. KJB
