It isn't Legalism that tells people to avoid alcohol.. It should be obvious to all that GODS word specifically states to not be drunken.. Gods word says to have nothing to do with drunkenness.. God as a Loving father warns us to avoid things that destroy our lives.. He pleads with us to not partake of those things that destroy lives!
All you have to do is look around you to see the Hell and destruction that alcohol can bring.
19 Now the works of the flesh are manifest, which are [these]; Adultery, fornication, uncleanness, lasciviousness,
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told [you] in time past, that they which do such things shall not inherit the kingdom of God.
29 Who hath woe? who hath sorrow? who hath contentions? who hath babbling? who hath wounds without cause? who hath redness of eyes?
30 They that tarry long at the wine; they that go to seek mixed wine.
31 Look not thou upon the wine when it is red, when it giveth his colour in the cup, [when] it moveth itself aright.
32 At the last it biteth like a serpent, and stingeth like an adder.
34 Yea, thou shalt be as he that lieth down in the midst of the sea, or as he that lieth upon the top of a mast.
35 They have stricken me, [shalt thou say, and] I was not sick; they have beaten me, [and] I felt [it] not: when shall I awake? I will seek it yet again.
Proverbs 20:1 - Wine [is] a mocker, strong drink [is] raging: and whosoever is deceived thereby is not wise.
Romans 14:21 - [It is] good neither to eat flesh, nor to drink wine, nor [any thing] whereby thy brother stumbleth, or is offended, or is made weak.
1 Timothy 3:8 - Likewise [must] the deacons [be] grave, not double tongued, not given to much wine, not greedy of filthy lucre;
Isaiah 5:11 - Woe unto them that rise up early in the morning, [that] they may follow strong drink; that continue until night, [till] wine inflame them!
