Indeed Religion is a tough subject. But some words are not religious even though they are found in religious writings. For example commandments. That always sounded harsh to me but rules seems less harsh. I prefer blessings. Matthew 5 in the New Testament speaks about them. Again more like rules of how to live rather than what to avoid. It’s sometimes easier for a child to understand and accept a belief than for adults who may have had little exposure to a belief as a child. I grew up in church so believing in something was taught innocently at a young age and progressed. I don’t try to know everything about religion I usually just start with a favorite topic and let my imagination wander beyond that. If you know nothing of religion then it can be very intimidating to know where to start. I always start with Matthew 5. It’s a simple place to start for some.
