Woe to you, O land, whose king is a lad,and whose princes feast in the morning.
Blessed are you, O land, whose king is of nobility and whose princes eat at the appropriate time, for strength and not for drunkenness.
-Ecclesiastes 10:17

To say that a thing good in itself is bad because sometimes abused,
is as absurd as to say that the beautiful Ohio river is an evil because it at times overflows its banks. -Walter Forward.

I like beer...but not any beer, I am particular about what I drink.
It always comes out of a tap or a bottle and never from a can.
It's not cheap and isn't drunk for the purpose of getting hammered.

Drunkenness is a sin (see lev. 10:9, Eph. 5:18 and 1 Timothy 3:3) and if you are drinking to get drunk, you are on the wrong path and it will lead to trouble.

If you are not 21 than you are breaking the law.

As a Christian we are called to obey the law and live our lives within the safe perimeters of God's law. His word is given to liberate us and set us free from destructive paths and false ideas, presumptions and beliefs about a truly spiritual life and how to live it.

Beware of excess and don't turn your freedom into an opportunity for the flesh.
Learn to be in control of your flesh and it's appetites.
Practice self-control and learn to be an example in how you use the things God has blessed us to enjoy. Slobbering drunks do not give God glory and neither does the typical conversation or actions that often comes when people drink too much.

All of that is the sign of immaturity and reveals that you are becoming overcome by what you are partaking in. By what a man is overcome, by this he is enslaved. -2 Peter 2:19
