If the Sabbath no longer applied, why did the Apostles after Jesus departed earth continue to honor the Sabbath?
Jesus told us the Sabbath was made for us, not we for the Sabbath.
The Book of Mark chapter 2: 27 And he said unto them, The sabbath was made for man, and not man for the sabbath: 28 so that the Son of man is lord even of the sabbath.
Why would we think Sabbath is no longer valid and yet go to church on Sunday, which is making that day the Sabbath day, even though it is on the wrong day.
The Book of Matthew chapter 19:16 And behold, one came to him and said, [
i]Teacher, what good thing shall I do, that I may have eternal life? 17 And he said unto him, [
j]Why askest thou me concerning that which is good? One there is who is good: but if thou wouldest enter into life, keep the commandments. 18 He saith unto him, Which? And Jesus said, [
k]Thou shalt not kill, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness, 19 Honor thy father and thy mother; and, [
l]Thou shalt love thy neighbor as thyself.
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. Therefore anyone who sets aside one of the least of these commands and teaches others accordingly will be called least in the kingdom of heaven, but whoever practices and teaches these commands will be called great in the kingdom of heaven. For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.”
The Book of Matthew Chapter 5:17-20
