Lotta difference between being 'merry' and wilfully voluteering to impair your own judgment.
1 Peter 5:8
Be
sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour
Giving men liquor, Satan beclouds their perceptive faculties, making them incapable of distinguishing between right and wrong.
Moderate drinking is the school in which people are educated for the drunkard’s career. Yet so insidious is the work of these milder stimulants that the highway to drunkenness is entered before the victim suspects his danger.
Many a Man has taken that first drink and then ended up killing someone else out on the highway, killing other peopel's families, and children. That first drink impairs their judgment and they have more and more until it is too late. That is why Alcoholics are warned not to even have that first drink and to abstain entirely.
This is why in Peter's Ladder, one of the rungs is TEMPERANCE. There is a reason why Daniel refused to drink the King's Wine, see Daniel Chapter 1. And he did not 'just have a little bit' of it. He abstained from it entirely. Daniel is an example for people who are living in the End Times. The Bible said because he refused to eat the Kings food and Wine, he and his friends were given the gift by God of being able to understand Bible prophecy. And they were ten times better off mentally and physically than those who worked under the King. Daniel and his friends were given a pulse Diet, meaning Vegetarian.
There are those in our day, who, in order to excuse their own sins, follow the example of the Jews, and charge Christ with being a Sabbath-breaker and wine-bibber, notwithstanding he declared that he kept his Father's commandments, and his whole life was an example of temperance and self-denial. Had he been a wine-bibber he could not have been a perfect offering, and the virtue of his blood would have been of no avail. But this charge, as well as the former, is best refuted by the character and teachings of Christ himself.
Christians should there be taught how unsafe it is to tamper with temptation, to dally with sin; that there is no such thing as being a moderate and temperate drinker; that the path of the tippler is ever downward. They should be exhorted to “look not upon the wine when it is red,” which “at the last biteth like a serpent, and stingeth like an adder.” But instead, many Churches are 'placing the wine-cup to their neighbor's lips' by telling them that they can be 'moderate drinkers'.
