Man cannot come to a rational understanding of anything behind the will of God. He can give his response to God’s commandment only through an act of obedience or disobedience, that is to say by his will.
Dihle argues that the Biblical framework uniquely constitutes human will as a moral category precisely because the will of God is opaque to reason, demanding personal response rather than intellectual comprehension.
