Don't know what you mean by commission. Were you commissioned to be here by God or some authority over you, your on commission getting paid?
Grace just means accepting that God has done something that you can never add to nor pay back in any way. God saves a man's soul least a man brags about his deeds. But he never gave a time frame. Read the table of shew bread, not until the last man walks the earth.
Fallen man can earn nothing meaning the only thing he can attain is the very same soul God gave him, he can't add nor create one.
Yet you say a fallen man can earn nothing, yet your on commission, clarify.
