Jakobus 2:19

Thou--emphatic. Thou self-deceiving claimant to faith without works. that there is one God--rather, "that God is one": God's existence, however, is also asserted. The fundamental article of the creed of Jews and Christians alike, and the point of faith on which especially the former boasted themselves, as distinguishing them from the Gentiles, and hence adduced by James here. thou doest well--so far good. But unless thy faith goes farther than an assent to this truth, "the evil spirits (literally, 'demons': 'devil' is the term restricted to Satan, their head) believe" so far in common with thee, "and (so far from being saved by such a faith) shudder (so the Greek)," Mat 8:29; Luk 4:34; Pe2 2:4; Jde 1:6; Rev 20:10. Their faith only adds to their torment at the thought of having to meet Him who is to consign them to their just doom: so thine (Heb 10:26-27, it is not the faith of love, but of fear, that hath torment, Jo1 4:18).

In this chapter the apostle condemns a sinful regarding of the rich, and despising the poor, which he imputes to partiality and injustice, and shows it to be an acting contrary to God, who has chosen the poor, and whose interest is often persecuted, and his name blasphemed, by the rich (Jam 2:1-7). He shows that the whole law is to be fulfilled, and that mercy should be followed, as well as justice (Jam 2:8-13). He exposes the error and folly of those who boast of faith without works, telling us that this is but a dead faith, and such a faith as devils have, not the faith of Abraham, or of Rahab (Jam 2:11 to the end).

2:19 that there is one God: This is the basic confession of Israel’s faith (see Deut 6:4). • the demons believe: They know that there is one God, and he is their enemy (Mark 1:24).
