What makes fermented wine such a blessing from just plain old grape juice is its ablility to make the heart merry, in other words, get a buzz going.
Psalms 104:15 And wine that makes glad the heart of man, Oil to make his face shine, And bread which strengthens man's heart.
Fermented wine can ease the pain of death and lift a heavy heart.
Proverbs 31:6 Give strong drink unto him that is ready to perish, and wine unto those that be of heavy hearts.
Oh don't get me wrong, God does not what His priest drinking while on duty.
Ezekiel 44:21 "No priest shall drink wine when he enters the inner court.
Lev.10:8-9 Then the Lord spoke to Aaron, saying: "Do not drink wine or intoxicating drink, you, nor your sons with you, when you go into the tabernacle of meeting, lest you die.
Because Aaron and his sons couldn't drink intoxicating wine while in the tabernacle tells me that they coud drink if they were not in the tabernacle.
Oh yah, what about the Nazirite. He too was not allowed to drink on duty but afterwards it was okay to have a cold Bud after a long day at the office, Bud light of course.
Numbers 6:1-5 Then the Lord spoke to Moses, saying, "Speak to the children of Israel, and say to them: `When either a man or woman consecrates an offering to take the vow of a Nazirite, to separate himself to the Lord,`he shall separate himself from wine and similar drink; he shall drink neither vinegar made from wine nor vinegar made from similar drink; neither shall he drink any grape juice, nor eat fresh grapes or raisins.`All the days of his separation he shall eat nothing that is produced by the grapevine, from seed to skin.`All the days of the vow of his separation no razor shall come upon his head; until the days are fulfilled for which he separated himself to the Lord, he shall be holy.
Numbers 6:20 And the priest shall wave them for a wave offering before the Lord: this is holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine.
What a blessing femented wine can be for thoes who know the truth. But for those who don't know the truth God tells us to treat them as weaker brothers and sisters.
Romans 14:21 It is good neither to eat meat nor drink wine nor do anything by which your brother stumbles or is offended or is made weak.
Many blessings,
John
