Christ is often referred to as the Second Adam. The first Adam, from Genesis was in paradise up to time he and Eve ate of the tree of knowledge of good and evil. This tree is symbolic of law of good and evil or right and wrong. The Old Testament was under law of good and evil, with the wage of sin or violation of the law, wrath and punishment. The second Adam brings us back to before law and before wrath. In paradise, God was nice and loving and very positive to Adam and Eve, like Jesus with children; paradise.
Turn the other cheek, requires we leave behind all our preconceived opinions and expectations of what we consider personally and collectively, right and wrong or good and evil. Stealing is a moral value judgement. Before law, stealing was more like sharing, where there are no personal possessions by law but only a pile of useful things the whole family of man uses. The return to Adam before the fall; second Adam, makes life simple, light, loving, and peaceful; children's toy box in a day care center.
Wrath, fear, and fear of punishment causes time to slow; fight/flight. When we are in fight and flight mode, things seem to move in slow motion. This slowing of time narrows the mind to the details of the important task at hand. When we are having fun, time speeds up ,such that hours can go by and it can seem like minutes. The net effect is law and wrath narrows the mind to a short term POV. It can't see the same bigger picture that fun can see, where hours go by instead of seconds. The context of the mind and its perception of reality is different between fear and love. Each impacts how one sees and draws conclusions for the same things because each is optimized differently in time.
As an example, say you feel fear so time slows and your mind racing. Someone takes your laptop. Because your mind is moving so fast in time, you may get more defensive about this, since you may need it in two seconds to appease the needs of fight or flight; the phone can ring at any time.
On the other hand if you are playing a video game and having fun with many levels to go, you may not even notice the laptop being used and return an hour later. It is not the same crime for the same action because your mind is averaging reality over the needs of hours and not seconds. Jesus was sort of saying slow the mind down with love and rest, so you could see the bigger picture and not remain sped in time via fear. With love reality looks different; the world looks beautiful and not scary. It was not just wise but based on science that would someday appear in the 20 centuries later.
The second Adam, like the first, is having fun in paradise with time in motion, day to day; vacation without cares and fears. There is little concern, for second by second, like with the micro management style of fear. Law was good and useful in terms of slowing down time, via fear, so humans could begin to see the details of reality; fear of god is the beginning of wisdom. Wisdom is perfected in love using its longer time perception; better time averaging of the details of laws into general principles of life; tree of life.
