Chette, you're stretching it pretty far on that one.
Your quote from Prov. 31 puts the emphasis on the wrong fellow.
4. It is not for kings, O Lemuel, it is not for kings to drink wine; nor for princes strong drink:
5. Lest they drink, and forget the law, and pervert the judgment of any of the afflicted.
6. Give strong drink unto him that is ready to perish, and wine unto those that be of heavy hearts.
7. Let him drink, and forget his poverty, and remember his misery no more.
If you're going to make any application to today from this then you'd have to say that the drinking is for the LOST man and not the saved. No born again Christian is poor in Christ Jesus, etc...
Rev. 1:5 And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,
6 And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.
Worse yet, you of all people using a verse in Deut. (considering its context fully) to make allowance for the sin of drinking booze today.
You're talking about (1) Jews (2) in their land (3) bringing a special offering (4) to special place (5) at a special time - yearly, and then (6) preforming a special ceremony
before the Lord.
If you can get that its alright for a Christian to consume alcohol out of that, you're streeeeeeeeeeeeeeetching it!
