I haven’t read this anywhere but it might be true – why did God make us first naively open, then naively shut – the answer is, as follows, we must be born with love, in love, loving; for this is the destination of mankind – seeing as we must know an emotion through actually living it, there had to be a good few years of this emotional feeling within us (and truly those who lack it, are not functioning on an emotionally healthy level, for they are unaware of the preciousness of unconditional-love and unaware that many naturally feel this) however this emotion on its own, is too open, like a kid driving a car – it is dangerous to be open to all – therefore, God needs to shut down that open feeling through abuse – fear introduced, and closed: wary, discerning; which has a very important benefit – but ultimately, then we must shift into the truth, for fear has many negative side effects (anger, resentment, jealousy etc.) and the truth of course is, that we have a dual-responsibility, to first and foremost adhere to the ethics God teaches (for the person in naïve-love is not ethical, for their love is an emotional instinct) and of course, through that we will do the EFFECT of love, namely, build a unified loving society!
