Romans 1:20

‘For the invisible things of him since the creation of the world are clearly seen, being perceived through the things which are made, even his everlasting power and divinity, that they may be without excuse,'

For what makes man totally inexcusable is that ‘the things that are made' reveal to the open mind the invisible things of God (His goodness, wisdom, power, majesty, creativity, providential care) and have done so from the beginning. For in combination with man's spiritual nature they make known His eternal power and Godhead. As we look at the wonders of creation, the evidence of ‘design' in nature, its beauty, its diverse colours, its radiance, the scene from the mountain top, the wonder of men's inexplicable bodies and minds (made even more inexplicable by the discoveries of micro-biology and the discovery of the human genome), and the wonders of outer space, we can only recognise that it is God Who has done this, a God Who is rational, interested in beauty, powerful, intricate, and yet Who brings comfort to the heart. As the Psalmist said, ‘The heavens declare the glory of God and the firmament shows His handiwork, day unto day utters speech, and the night-time is not silent' (Psalms 19:1). And Jesus added, ‘Consider the lilies of the field, how they grow, they toil not neither do they spin, and yet I say to you that even Solomon in all his glory, was not arrayed like one of these' (Matthew 6:28). These ideas of design, magnificence and beauty should therefore fill us with awe and point our hearts towards God, and would in fact do so were we not blinded by sin. But the problem is that men do not want to know God. So instead men philosophise them away.
