In many situations the person can consider doing and refraining from an action. Religious obligation addresses someone able, under the relevant conditions, to understand the command and direct conduct accordingly.
For example, a person can intend either to return a trust or to withhold it. Divine creation applies to what occurs, but returning the trust is commendable and betraying it is blameworthy.
Choice is not equivalent to independence from God's will. It is a feature of the servant's action and accountability, not a license to claim autonomous creative power.
