The people of Sodom and Gomorrha did not want any restrictions, and they wanted to explore and to indulge themselves sensually in whatever they felt was open to them. This third example shocks us.
Is this sin really against nature? The teaching of Scripture is that human beings come into this world with a fallen nature which produces fallen desires. Some imagine that their responsibility begins where their desires end. They imagine that they are not responsible for desires themselves since they arise from nature, and nature is a given. They therefore excuse their behaviour as driven by desires which are innate. 'I cannot help doing these things, God made me attracted to them'. This is a great mistake. They forget that the nature we have now is not the nature that God created, but a fallen nature. What they therefore call ‘natural’, God calls 'unnatural' for the nature by which they justify themselves is that corrupt nature which they perversely approve. But when the Scripture charges them with being unnatural, it does not deny that their sins originate in their nature; only it insists that the nature is not what God originally made. It is relatively easy for human beings to reprogram their desires in accordance with this fallen nature within them. In truth, we are held responsible by God not only for our actions, but also for our desires and even for our nature. This last produces in man the greatest outrage of all and yet from the earliest age, he gives evidence that he approves of this nature. 'But what can you do against his nature?', you ask. Indeed, repentance and conversion are an attack upon our own nature by ourselves. Under conviction of sin we condemn ourselves and we justify God; we acknowledge that we have broken his laws and brought guilt upon ourselves so that we are without excuse.
