Yakobus 3:14

3:14 But if you have bitter jealousy and selfishness in your hearts, do not boast and tell lies against the truth.

Yakobus 4:8

4:8 Draw near to God and he will draw near to you. Cleanse your hands, you sinners, and make your hearts pure, you double-minded. ¹ 

Yakobus 5:5

5:5 You have lived indulgently and luxuriously on the earth. You have fattened your hearts in a day of slaughter. ² 

[4:8]  ¹ tn Or “two-minded” (the same description used in 1:8).

[5:5]  ² sn James’ point seems to be that instead of seeking deliverance from condemnation, they have defied God’s law (fattened your hearts) and made themselves more likely objects of his judgment (in a day of slaughter).
