The Bible defines faith in strikingly absolute terms:
“Now faith is confidence in what we hope for and assurance about what we do not see.”
— Hebrews 11:1
For years, I lived inside that definition. To believe in God, in the death and resurrection of Jesus, in heaven and hell, was not to speculate but to be certain. I remember how real that certainty felt — as if the ground beneath me could not possibly give way.
Looking back, I can still see why conviction is so attractive. It simplifies life. It gives you direction. There’s something reassuring about being guided by a strong sense of rightness, rather than drifting on vague, half-formed notions. For a time, I admired that in myself and in others — the courage to stand firm, to be sure.
But certainty has a darker side. It divides the world into believers and non-believers, insiders and outsiders. I’ve seen how quickly that division hardens into judgment, superiority, even hostility. History is full of examples where religious certainty did not just separate communities but helped justify oppression and war. That recognition has been painful for me, because I once participated in the same mindset.
Doubt, by contrast, has never started wars. It doesn’t silence art or suppress science. If anything, doubt has opened doors — for creativity, for discovery, for dialogue. In my own life, doubt has forced me to pause, to ask questions I once thought dangerous. Strangely enough, it has made me more compassionate. To give someone the benefit of the doubt, even in ordinary relationships, is to allow space for understanding rather than condemnation. On a larger scale, when whole cultures are willing to live with doubt, it creates the possibility of cooperation instead of conflict.
For me, the shift from certainty to doubt has not been easy. It feels like stepping off firm ground into open air. But it also feels more honest. Faith, I now see, is not always confidence; it can just as easily be the refusal to face uncomfortable truths. Doubt, far from being weakness, has become — for me — a condition of dignity, the beginning of humility, the chance to meet others without the armour of superiority.
Voltaire once wrote:
“Si Dieu n’existait pas, il faudrait l’inventer.”
If God did not exist, it would be necessary to invent him.
Perhaps he was right. But if we are honest with ourselves, we may also need to invent doubt — not as a threat to our humanity, but as its safeguard.
