f I don't believe in a loving God, one that won't expel my 5yo neighbor from church because he's in a wheelchair, or my son, because he's an Aspie, then I cannot believe in God. I don't believe any power who is said to have created life would so willingly cast those aside who are not perfect.
Only he shall not go in unto the vail, nor come nigh unto the altar, because he hath a blemish; that he profane not my sanctuaries
They weren't expelled from the entire area, just prevented from going up to the altar, just like blemished animals couldn't be sacrificed on the altar. Similarly, the "unclean" had to stay outside the camp, but the priests still went out to take care of them, it's not like they were just kicked out and left to die because they weren't perfect.
But in any case, this was Old Testmant law, not New Testament, and most of it doesn't apply now that Jesus has arrived. Blood sacrifices, for instance, were an "image" of the coming sacrifice of Jesus, which is why everything involved had to be perfect.
t's not positive as in happy-rosy positive, but positive as in a positive direction. There's no retribution, no eye for an eye, everything is considered a teaching moment to help the child grow to adulthood. The entire outlook of discipline is changed to "what can we learn from this?" or "how can we stop the problem?" and looks toward treating the cause, not the symptoms, or if the child is too young, then using age appropriate methods that work with their limitations. It's hard to explain, but there's many books on it, including Christian ones like Grace Based Parenting. I wrote a short list that sums it up, too, that seems to explain more if anyone wants to read.
There's a big difference between random pain and/or suffering being applied whenever someone does something you don't like, and x penalty being assigned in advance for y offense, then enforced. The former has little or no positive effect, the latter is effective for training.
