Question:
What does: “Sin, when it is finished” in James 1:15 mean?

Answer:
The word “finished” in this verse means full-grown, fully completed. Joshua 7:20-25 is an example of this. If we sin, we have to cover up that sin with a sin, and so on. But we have a choice after each sin to confess and stop.

If we keep sinning then sin will be “fully completed” by death. For the unsaved it means the second death in the Lake of Fire.
