When a Year 9 student asks 'If God is real, why does he allow children to suffer?', they are not trying to destroy your faith. They are asking a question that bothers them, testing whether Christianity can hold the weight of reality, and — often — secretly hoping you'll have something worth hearing. Take the question seriously as a gift, not a threat.
Hard Questions Are a Gift
The Problem of Evil
This is the hardest question in all of philosophy, and it has serious engagement in Christian thought (Alvin Plantinga's free will defense, C.S. Lewis's The Problem of Pain, Tim Keller's treatment in Walking with God through Pain and Suffering). You don't need to have read all of these; you need to be able to say: 'This is a real and serious question. The Christian answer is not that God doesn't see it — it's that God entered it. The cross is God's answer to suffering, not his absence from it.'
Science and Faith
The science vs. religion framing is a 19th-century myth, not a historical description. The founders of modern science — Newton, Kepler, Faraday, Collins — were Christians who saw science as exploring God's creation. The question of origins (how did life begin?) is philosophically distinct from the question of existence (why is there something rather than nothing?), and Christianity speaks to the second in ways science does not. Help students see these as complementary questions, not competing answers.
Doesn't Christianity Arrogantly Claim to Be the Only True Religion?
Every worldview makes exclusive truth claims — including atheism, which claims there is no God (exclusively). The question is not whether exclusive claims are arrogant but whether they are true. Jesus said 'I am the way, the truth, and the life.' Either he was right, wrong, or mad. What you can model for students is the difference between confidence and arrogance: you can hold firm convictions while remaining genuinely curious about others' views and genuinely kind in disagreement.
