Mark 10:20
Teacher, he declared, all these I have kept since I was a boy — the man's claim is not presented as false or delusional but as his honest self-assessment. He has lived a life of Torah obedience from childhood — a genuinely moral, law-observant life. The claim is not the problem; the assumption behind it (that eternal life is achievable through commandment-keeping) is. He has done everything he knows to do, and he senses it is not enough — which is why he is asking the question.
