Paradox #1
The verse suggests that nature follows consistent rules, like a tree producing one type of fruit. This might seem to conflict with other biblical teachings that describe miracles or actions that defy natural expectations, like Jesus turning water into wine. However, such acts are often seen as divine interventions rather than contradictions, so overall, there's no major doctrinal conflict.
