How are we to understand the interrelationship between these two attitudes? What balance does God strike? And what balance should we strike?
The answer lies in the character Isaac whose birth and early life is the core narrative of this week’s reading.
Isaac’s very name means laughter. Laughter characterises the vast majority of encounters he has. When Abraham first hears he will have a child, he bursts into laughter, later when Sarah hears a messenger deliver the good news, she too laughs. When he is actually born, Sarah declares, ‘all who hear will laugh with me.’ When his older brother seeks to harm the child, it is descried as laughter, presumably in the sense of mockery. Even his relationship with his wife Rebecca is described by the Torah as laughter.
Clearly something about Isaac’s life is deeply connected with laughter. What is that connection?
One powerful suggestion is that laughter is the instinctive human response to something sudden and unexpected. A great punchline that twists the meaning of the lines before it, or that crosses lines others would not, or that shocks, can all evoke laughter.
Creation is the ultimate unexpected. God has no needs, so there is no ‘reason’ for creation. It is the purest possible choice ever made: one for which there was no demand. Creation addresses no need and responds to no problem. It is an act of pure Will and nothing else. In that sense, it is the greatest act of humour possible.
Creation is inherently unequal. God is the giver, we are the takers. We give God nothing in return for creation. That is why creation is the greatest act of altruism, and unconditional giving; the very act of creation is the purest selfless love there can be.
But that very unevenness creates in its wake an enormous problem. On one level it can be stated like this: to be in this totally unbalanced relationship which we never chose means we lack any sense of dignity whatsoever. We may be the takers, but there is nothing nice about being a taker. God may have Willed the purest act of loving and giving, but that act of loving and giving cannot find a recipient when all there is pure giving and pure taking.
Another way to consider the problem is this. God is, as it were, thinking the world into existence. We can also think a world into existence. We can dream up all sorts of beings and creatures. But they never truly exist. They are all just figments of our imagination. Our consciousness fills them, and leaves them no room to feel themselves.
So we have the problem of creations who lack dignity, and we have the problem of creations that lack awareness. They are deeply related. And they are solved in exactly the same way: by creating the space for the created beings to choose to receive the very life, existence and love that is being offered.
The Kabbalistic doctrine of ‘tzimtzum’ describes a process of ‘withdrawal’ through which God creates space for man to exist. It seems impossible to us. After all, to the extent to which God thinks something into existence God fills it and it has no sense of self. To the extent to which God withdraws his thought, that entity is withdrawn from existence. The answer is that God somehow creates a vision of creation that is complete and whole, and then withdraws partially from it, leaving a faint withered shadow of the former creation that lies delicately poised between existence and non-existence.
We cannot fully understand this process because we ourselves cannot actually do it in our minds. But the result is that we end up with a being that is torn between existence and non-existence. Between connection to God and detachment from God. That being has freewill, and that freedom produces and actual autonomous mind that is aware.
Freewill also means that even though creation is an act of love and giving, we do not immediately receive anything. We have to use our minds and our will to choose to connect to God. We could instead choose to reject God, and embrace non-existence instead. The allure of illusion is immensely powerful. It takes immense effort to choose to connect to God, to choose to receive His goodness, and to choose to allow His plan, dream and vision of creation, to come to fruition.
In an incredible completion of the circle, our effort not only earns our reward; it is our reward. We deserve and earn our reward by choosing to connect to God. The reward is that we are connected to God – the ultimate Infinite Source of all good. To the extent we do good, we earn good. To the extent we violate good, we lose good. That is where justice is born.
The root of justice is the same as the root of evil. Both come into existence the moment God creates space for a free-will being to exist.
Both are the result of His desire to give.
Avraham began his journey by discovering that creation is an act of pure love. For Avraham there could be no room for justice, even in the face of evil. The anti-kindness nemesis culture of Sedom seduced his own nephew and heir from his side leaving him bereft. Yet he did not seek justice or punishment. Instead he fought for them, and he prayed for them.
But this week he learned that lovingkindness can never truly exist when all that there are are givers and takers. The giver must leave a space for the taker to earn their gift. Without justice there can be no true kindness. This is why the highest level of charity is not to give to someone, but to employ them; to allow them to earn the gift.
Avraham received a free gift in his child Isaac, as unearned and unexpected as creation itself; something that can evoke only laughter. But after being taught again and again the value of justice, of ‘fear of God’, that he was ready to truly earn the existence of his son. In the ultimate test, the binding of his own child, in the willingness to sacrifice everything for God, ironically, he came to earn that very gift. He proved himself to be one who ‘feared God’ and in doing so he earned the love of God.
Vayera teaches us that a relationship is only as strong as our ability to choose it. The gift of love is at its truest when the lover does not try to control the recipient of it, but creates the space for them to grow into their own.
That is the secret of creation that is revealed in this week’s teaching. It is that the ultimate gift that God gave to us was not creation, but the ability to earn it.
We all want a world of unconditional loving kindness. We all want a world of justice. To the extent to which we can justly earn our existence, is the extent to which we can receive and share the Creator’s love and kindness.
