We as Christians are Priests! A HOLY priesthood!
In the book of the Law of the Priests (Leviticus) we read:
Leviticus 10:9
Do not drink wine nor strong drink, thou, nor thy sons with thee, when ye go into the tabernacle of the congregation, [Church] lest ye die: it shall be a
statute for ever throughout your generations:
Judges 13:4
Now therefore beware, I pray thee, and drink not wine nor strong drink, and eat not any unclean thing:
Let us too separate ourselves from any ungodly influences so that we may found "blameless" when Christ returns.
Jesus whom we should emulate, took a special vow because he was a Nazarite:
Numbers 6:2-4 (King James Version)
2Speak unto the children of Israel, and say unto them, When either man or woman shall separate themselves to vow a vow of a Nazarite, to separate themselves unto the LORD:
3He shall separate himself from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried.
4All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk.
