Once someone is able to appreciate the entire structure of religion including it’s foundation based on natural disposition, and evidence-based belief in the God, the prophets, the day of judgement, and the scriptures, then questions like whether or not God can lie become completely irrelevant. Ghamidi sahab actually did address the reason why in the same video, but I agree that his explanation will only make sense if one is able to understand and appreciate the fundamentals at a deeper level. For reference, following is the video that you referred to. https://youtu.be/fGkDTi8wdow
