"The fact that we have free will, to choose [righteousness] or not, means that we have been granted the capability of doing enormous good and immense harm. We can find a cure for cancer or we can blow ourselves to bits: it's entirely up to us. But in order for free will to work, God has to set a limit to Divine power; if we are to be free agents morally, God may not intervene and deprive us of that capability... In other words, God has removed human behavior from the sphere of Divine control and influence."
~Rabbi Simcha Roth
