Jer 18:23 Yet you, O LORD, know all their plotting to kill me. Forgive not their iniquity, nor blot out their sin from your sight. Let them be overthrown before you; deal with them in the time of your anger.
In Jeremiah 18, Jeremiah is sent to preach to a people group which hates him. He calls on God to judge these people. Interestingly, Jeremiah prays that God punish them “in your time of anger”. Dealing with them in God’s time of anger is meant to increase the severity of the punishment. This suggests that Jeremiah believes that God’s emotional disposition is one input into God’s actions. Jeremiah is highlighting God’s passions.
