God creates free will, His greatest accomplishment. By asking what is contrary to nature, one can choose between Law and natural tendencies. By saying we disobey his Word, one can choose to disobey or obey as both ways fulfill the Word. By introducing contradictions into His Word, he gave us the right to choose. Sacred Texts are full of contradictions for this very reason: the more God contradicts himself the freer we are. God then contracted his power as to open a space for our freedom: that is the essence of God’s self-sacrifice.
