It's wrong for Christians to continually update the Bible and bring it up to modern times, it's an abominable offense (Revelation 22:18-19). It's the duty though of Christians to spread/preach the Word.
The Bible doesn't grow, it doesn't evolve either. Di po pwedeng magbago ang Bible, otherwise God is a compromising god. Di po sya ganun.
Christ did not overturned that ruling. During the OT times, the punishment for breaking the Sabbath day is death. Ganun kahigpit ang Diyos. During Christ's time, the penalty is still death, but not physical death, rather it's spiritual death. Meaning, if you break the Sabbath day, you'll not be killed, but you're commiting a sin.
Books cannot be added to the Bible because of the above curse. There may be people who did this, or are doing it, then it's their choice, they've been warned. Now why doesn't it continue until today? The job of the prophets was to bring Christ to every people, nation, tribe of the world, using the Bible. Today, it's the job of every Christian to continue what the prophets did, to evangelize, to bring Christ to every modern people using not just the Bible but every available means of communication.
This I agree, ganito rin kasi ang sabi ng Diyos, subukan Sya. And this should be the attitude of all people.
This I beg to disagree, because as I've said, God is not a compromising god, He's holy and righteous, though a lot of Christians today are compromising their faith and beliefs.
Again it's their choice.
