In "Are You Drinking of the Master's Cup?" (Forerunner, March 1999), the author tells of an ancient Hebrew tradition: When a young man and woman were to be betrothed (engaged) for marriage, the groom poured wine into his cup and invited the woman to drink of it. The choice was hers: If she drank from it, she was considered betrothed to the young man. She was agreeing to experience all the things that his life entailed, the good as well as the bad. When the woman drank of the cup, she drank of the marriage covenant and accepted it. Paul refers to this when he tells the church in II Corinthians 11:2: "For I am jealous for you with godly jealousy. For I have betrothed you to one husband, that I may present you as a chaste virgin to Christ."
As Jesus sat at His last Passover with His disciples, He poured wine into His cup and blessed it, telling the disciples, "Drink from it, all of you. For this is My blood of the new covenant, which is shed for many for the remission of sins" (Matthew 26:27-28). By literally drinking from His cup, they each accepted the terms of the New Covenant. It was a symbolic betrothal or engagement of the church, the Israel of God, to Christ. This is part of what we commemorate with each Passover service—our spiritual engagement to Christ, which will culminate with the marriage feast after He returns (Revelation 19:9).
Before we were called out of this world, we all walked according to the course of the world (Ephesians 2:2-3). We were the sons and daughters of disobedience, conducting ourselves in the lusts of the flesh, fulfilling the desires of the flesh and mind. We drank from the cup of Babylon by ingesting a false religion and the culture around us that God says is filthiness (Revelation 17:1-6; 18:1-6).
This is why God tells us to come out of Babylon—so that we do not share the sins in her promiscuous cup and the consequences that God promises He will pour out upon her.
Formerly, we were slaves to sin and its consequences. Now, under the New Covenant, we drink from Christ's cup and agree to His terms. This frees us from the death penalty of sin as well as making us responsible to remain faithful to this spiritual engagement.
Paul warns us that God is jealous toward His people, and that they must choose to whom they will be loyal: "You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the Lord's table and of the table of demons. Or do we provoke the Lord to jealousy? Are we stronger than He?" (I Corinthians 10:21-22).
It is plain that we must make a choice: We either drink of the cup of Christ and remain faithful to our commitment, or we drink of the cup of demons and the sinful system they rule. These two cups are mutually exclusive. We cannot have both!
If we have drunk from Christ's cup, can we continue to sip from the cup of this world's culture or its false religious system? Can we drink of His cup, accepting His proposal for marriage, and still have intimate interactions with Babylon? Even in our morally debased secular world, this would be grounds for nullifying that covenant of future marriage.
