There is always a new idea. People change their ideas because of the new idea. I know that idea is temporal because man said it.
There are rules that are forever. The forever rules is the Bible. The Bible is always true. The Bible was true, the Bible is true and the Bible will be true. God is the same. He never change.
The grass withers and the flowers fall, but the word of our God endures forever.”
17 “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.18 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.19 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.
31 Heaven and earth will pass away, but my words will never pass away.
