Paradox #1
1 Timothy 1:13 talks about someone receiving mercy despite their past wrongdoings because they acted out of ignorance and unbelief. A potential contradiction could be the idea that ignorance excuses wrongdoing, which might conflict with the belief that people should be held accountable for their actions regardless of their understanding. It might seem inconsistent with the expectation to uphold moral standards at all times.
