Paul begins by establishing his authority as an apostle. He did not always say this.
All the knowledge we have of divine things is given. We need to emphasise this, obvious as it is, because things have changed, and we live in a time and a society when revelation, given values, absolute standards, are hated and detested. Society has decided that there is no such thing as absolute, definable, knowable truth. That is nonsense, they say. There is no such thing as immovable, given truth. Everything that we think and know and do is subject to human reason. And in this last fifty years we have passed through various phases of this, post-modernism, nothing can be known, nothing is true. But now the realisation that you do have to have a framework, and you do have to have some ethical standards, and you do have to have some explanation as to why society behaves as it does and human nature works as it does. But every decade the ideas have changed. Now it is reason and not revelation, and the ideas of the 70s have already passed, and the ideas of the 80s are already ridiculed, and the ideas of the 90s are only half there and they are being replaced. We are into this situation now of human reasoning, finding new and different explanations. Right now, we are into the hierarchy of oppressions, and who knows what will come next. But there is muddle and confusion. How precious it is that when it comes to knowledge about God and the faith, and how to find him and live for him, these are not subject to human thought but they are given. So we have to exalt the term, apostle: God speaking, the closing hours and days of revealed truth, the doctrines of the New Testament.
