Jesus drank the cup of God’s wrath for us so that he could extend the cup of God’s fellowship to us. It might include suffering, but not wrath. We don’t get wrath anymore — now we get God. We get the sweet, satisfying reality of his eternal fellowship in Jesus Christ, through the Holy Spirit.
This is the cup we drink now and forever. This is the cup that we offer to those who don’t know him yet, imploring them in God’s mercy, Come, drink this cup with us because Jesus drank that cup for us.
