I don't agree that James tells us where sin actually originates from, as in the Universe. He is talking about our personal sins
I believe that sins are personal (I don't mean that sarcastically but theologically).
Let's look at the passage -
James 1:13–17 Let no one say when he is tempted, “I am being tempted by God”; for God cannot be tempted by evil, and He Himself does not tempt anyone.
14 But each one is tempted when he is carried away and enticed by his own lust.
15 Then when lust has conceived, it gives birth to sin; and when sin is accomplished, it brings forth death.
16 Do not be deceived, my beloved brethren.
17 Every good thing given and every perfect gift is from above, coming down from the Father of lights, with whom there is no variation or shifting shadow.
At the onset we can know without a doubt that God does not author sin. But what can we know about the origin of sin?
Sin originates with lust and sin brings forth death.
It is our own desires of the flesh that creates sin. We saw this with Adam in the Garden as he ate the desirable forbidden fruit. We saw this with Satan as he desired that which belonged to God.
And this is personal sin as it originates with each of us.
