Paradox #1
The verse in question emphasizes assurance of eternal life for believers. A potential contradiction or inconsistency might arise if one interprets this assurance as promoting complacency, leading someone to neglect moral responsibilities or personal growth, relying solely on belief for redemption instead of actions. However, this interpretation heavily depends on an individual's perspective and broader understanding of biblical teachings about faith and works.
