Is it God?
Is it something God gives us?
same thing to me... humans with out God are nothing good.
Is it part of us or an outside force placed within us?
Gen_1:2 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
IMO this is the over all thing...Which is apart from the indwelling of the Holy Spirit
Do the members of ISIS have this same force within them, telling them right from wrong?
Are they not doing what they see as being right?
Does that make them right?
ISIS does not kill everyone.
do you have to kill every one to be evil.
So they see a right to let certain people live.
And they see a wrong to see others get killed.
Rom 3:10 As it is written, There is none righteous, no, not one:
Rom 3:11 There is none that understandeth, there is none that seeketh after God.
Rom 3:12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
Rom 3:13 Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:
Rom 3:14 Whose mouth is full of cursing and bitterness:
Rom 3:15 Their feet are swift to shed blood:
Rom 3:16 Destruction and misery are in their ways:
Rom 3:17 And the way of peace have they not known:
Rom 3:18 There is no fear of God before their eyes.
How do we distinguish what is right and wrong unless we are in agreement as to what it is?
You wished to exclude Bible and God from the discussion IMO that cant be done...
Did Cain know it was wrong when he killed Abel?
The account in Gen 4 tells me he did..
Do you see all my questions?
One question may contradict another.
Where do we go with it?
There is only one place to go .. the Cross of Christ.
