Beer, Bohemianism, and True Christian Liberty
I replied the following to criticism of the Blog post by John MacArthur(with a few minor edits for here)that someone posted online:

I found what MacArthur said as edifying. In flaunting freedom some people get into trouble and get others into trouble...sometimes freedom is actually inviting sin...like watching immodest people and lusting and filling your mind with foul language that gets stuck in your head and eventually may come out of your mouth. Is that helpful? Encouraging someone to drink isn't helpful...not that a little alcohol is a sin. I don't drink, and people shouldn't start just out of a rebellion to their elders. Some verses that might be helpful: "For you were called to freedom, brethren; only do not turn your freedom into an opportunity for the flesh, but through love serve one another. For the whole Law is fulfilled in one word, in the statement, “YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF.” But if you bite and devour one another, take care that you are not consumed by one another. Galatians 5:13-15 NASB "Beloved, I urge you as aliens and strangers to abstain from fleshly lusts which wage war against the soul. Keep your behavior excellent among the Gentiles, so that in the thing in which they slander you as evildoers, they may because of your good deeds, as they observe them, glorify God in the day of visitation." 1 Peter 2:11-13 NASB "Act as free men, and do not use your freedom as a covering for evil, but use it as bondslaves of God. Honor all people, love the brotherhood, fear God, honor the king." 1 Peter 2:16-17 NASB
I respect John MacArthur.
