James 5:5

5:5 You have lived indulgently and luxuriously on the earth. You have fattened your hearts in a day of slaughter. ¹ 

James 5:8

5:8 You also be patient and strengthen your hearts, for the Lord’s return is near.

[5:5]  ¹ 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).
