Forgive me if I'm covering old ground here, but as I don't have time to read through 23 pages of posts, I'll just answer the OP directly...
I don't believe that God's "commands" are literally extrinsically-imposed orders, as a military officer would give orders to the troops under his command. Rather, I believe that (in their most basic sense, anyway) God's "commands" are built into our nature as human beings and are learned naturally as moral laws. Thus, what God "commands" us to do is, at its most basic level, built into the
Natural Law that we learn via natural reason.
Now, I suppose it
might be the case that God would literally command us to do this or that, but he would
not command us to behave in such a way that fundamentally violates his own more basic set of laws that is written into the natural order. We can therefore be certain that any order commanding us to do something that is
obviously morally evil (such as murder) cannot come from God.
