The Australian Labor Party, which is in government in Australia at present, has just changed its policy on same-sex marriage. It now supports it. Soon there will be a vote in the Australian Federal Parliament on whether or not to legalizes it.
This has been a controversy for a while now, with some states in other Western countries legalizing it, some nations in Europe recognizing same-sex marriage. Much of the opposition to the idea has come from members of the monotheistic faiths, Christianity, Judaism and Islam. Whatever their disagreements about other things, they concur on this: homosexuality is not just an individual variation like left or right handednes. It offends God.
Some practitioners of the faiths, calling themselves 'progressive', support homosexual marriage. All the arguments about minorities' rights, equality at law, love being the most important thing, have been voiced in support of homosexual rights. It raises the point here: God does not change to suit human fashion, God's Word does not alter to suit changing social views. God's Word in eternal and unchanging, and that is the reliability of it. We can know it now and always. If people believe that saying "This is the Twenty First Century" proves that everything has changed, they might learn the hard way that "there is nothing new under the sun." The Bible warns, and some secular history shows, that societies can become too self-satisfied with their own power and sophistication, become corrupt and implode from their own rottenness.
We might find that turning from God's Word does not usher in a new dawn of human well-being and joy. We have turned from God, scorned His guidance and sovereignty, and His blessing will pass from us. It would be shocking to see, but just as so many great empires and civilizations have fallen before, the modern world as we know it may collapse because human arrogance and blindness has become a trap for us and we led ourselves right into it. We thought we knew more than we did, and found out how little we knew. There may be a cataclysm into which we fall, or we may simply see a turning of the tide and a return to more Godly living, after some bitter lessons. That has happened before. Only God knows what He will do. One Christian friend remarked that she thinks this society is under judgement now.
Come again, Lord Jesus.
