Chuck Smith emphasizes the significance of Jesus drinking the cup of God's wrath, a metaphor for divine judgment, as prophesied for Edom. He explains that while Edom will face judgment, Jesus willingly took on the sins of humanity, becoming the ultimate sin offering in the garden of Gethsemane. Smith highlights the agony of Jesus as He prayed to the Father, expressing His reluctance to drink from the cup of wrath, yet ultimately submitting to God's will for the sake of salvation. The sermon underscores the choice each individual faces: to accept Jesus' sacrifice or face the consequences of their own sins. Smith concludes with a call to recognize the love of God and the importance of accepting the forgiveness offered through Christ.
