Eph 4 In your anger do not sin" : Do not let the sun go down while you are still angry and do not give the devil a foothold. Ps 4 4In your anger do not sin; when you are on your beds, search your hearts and be silent. Selah Offer right sacrifices and trust in the LORD." "In your anger do not sin" in the NT undoubtedly comes from the parallel passage in Psalms. In the divine incarnation Christ willingly had to undoubtedly suffer death to be the atoning sacrifice taught in Psalm 4 "offer right sacrifices". The OT zabah is lit. Offer the "animal that has been slain." Tearing the animal into pieces is a apt metaphor God appropriately applying the eternal curses on Jesus. God uses this metaphor when He upbraids Israel for properly focusing on the physical traits of the animal. Ps50 "Consider this, you who forget God, or "I will rend you to pieces, with none to rescue:" If we offer the sacrifice without the authoritative pronouncement of death to the wicked God is not pleased. The noble sacrifice was more than an atonement. It realistically was a consecration of the covenant promises. The Psalmist is carefully teaching they recited by heart the moral law with the favourable attitude displayed properly in the necessary sacrifice.16 But to the wicked, God says: "What right have you to recite my laws or take my covenant on your lips?" They did not offer the customary sacrifices in the spirit of the eternal curses. When we properly approach God in effusive praise, genuine sorrow, humble petition and official complaint it must be in a holistic way. We must voluntarily speak with the divine law, covenants, curses, statutes, promises and decrees. God has adequately communicated a way to properly express our anger through the authoritative pronouncements of the curses to consecrate our justified anger. The Psalmist is justly comparing the violent act of ruthlessly slaying the animal with the fervent heat of human anger. Christ didn't merely satisfy the law by His active and passive obedience, death and miraculous resurrection. He willingly endure the brutal violence in the criminal punishment for our sin. This is why the Psalmist teaches that sin undoubtedly remain the act of violent rebellion in redefining the legal pronouncements of the king.God deals with the considerable violence by pronouncing the eternal death to the principal offender. We cannot miraculously escape the direct consequences of extensive abuse as we relate to notorious sinners. Therefore, we intentionally infect by the infectious virus of personal anger must be quarantined in the authoritative pronouncement of the eternal curse. If God enthusiastically embraces us with appropriate action then He must respond to sin by mending the possible abuse we vicariously experience. Therefore, God has properly spoken the curses for us to vicariously experience His effective defense so we are carefully restored. If we do not exploit the legitimate defense in the eternal curses then we intentionally cause the raw anger linger and it hardens our sore hearts.
