Few words are as powerful as ‘why?’ When it comes to what our neighbours think, ‘why?’ helps us understand. When discussing issues of importance with our neighbours without a Christian worldview, it also helps us, and maybe them, to see that the worldview they hold is founded on shifting sands.

Consider your average secular Aussie. They believe people are the result of millions of years of chance mutation and natural selection. In this worldview, we are no different from the animals, simply more highly evolved.

But if that is the case, why do they believe people have value? It is still innate in our neighbours to believe that people should be treated well, and they are outraged (rightly) by the abuse and violence they see. They are horrified by atrocities like child sexual abuse, rape, murder, and other acts of violence.

In the issue of abortion, there are women out there offended that their ‘rights’ over ‘their bodies’ are even being discussed, that abortion is still something to be debated. They believe that they should have bodily autonomy.

But why believe this? They have strong moral beliefs (some of them right, and some – like their commitment to abortion – is tragically wrong). But where do these come from?

According to their worldview, we are a random collection of molecules. Our thoughts are random chemical reactions in a random brain. So why do they act as if their belief about morality is so right? How can they trust it?

Their instinct that there is a true morality we should uphold (even if their understanding of it is woefully wrong) only makes sense in the Christian worldview, where people are made in God’s image (Gen 1:26). The next time you speak with someone and they make a morality claim, try asking them why.
