dis-'man-t&l

I've heard the argument that in certain cases, using profanity can help your witness. I thought that I believed it was left up to the individual and relied heavily upon the context of the situation, but I'm beginning to question that idea.

And where does the idea come from that we have ANYTHING to do with "witnessing"? I was under the assumption that the Spirit, the Helper, is what leads someone to the Father. The only thing we can do is make our bodies a temple for the Spirit, feeding it through prayer, holy living, and time in God's Word; starving our flesh.
"Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers."
[Ephesians 4:29]
"But fornication and all uncleanliness or covetousness, let it not even be named among you... nor foolish talking, nor coarse jesting..."
[Ephesians 5:3-4]
"But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth."
[Colossians 3:8]

Let it not even be NAMED among you, let NO word proceed. This stands out to me. It doesn't say, based upon the context of the situation, decide if you should use "foolish talking" or "coarse jesting" to aid your witness.
"...because of these things the wrath of God comes upon the sons of disobedience. Therefore, do not be partakers with them."
[Ephesians 5:6-7]

Foolish talk and coarse jesting are included in the above list, and it is stated that God's wrath will be poured out on those who are not saved by Christ, therefore, don't join them because they're paying for their disobedience. Instead...
"...be filled with the spirit... speaking to one another in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord, giving thanks always..."
[Ephesians 5:18-21]

It seems here you could conclude that straying from "foolish talking" and replacing it with "spiritual songs and thanks" is evidence of being filled with the Spirit. This leads me to believe that the Spirit has no part with "foolish talking" and "coarse jesting" and does not lead someone to partake in them for the sake of witness.

As far as the argument for freedom in Christ, yes, you have freedom in Christ, but the second it becomes a stumbling block to someone else, it's sin.

1 Corinthians 8
Be Sensitive to Conscience
1 Now concerning things offered to idols: We know that we all have knowledge. Knowledge puffs up, but love edifies. 2 And if anyone thinks that he knows anything, he knows nothing yet as he ought to know. 3 But if anyone loves God, this one is known by Him.

4 Therefore concerning the eating of things offered to idols, we know that an idol is nothing in the world, and that there is no other God but one. 5 For even if there are so-called gods, whether in heaven or on earth (as there are many gods and many lords), 6 yet for us there is one God, the Father, of whom are all things, and we for Him; and one Lord Jesus Christ, through whom are all things, and through whom we live.

7 However, there is not in everyone that knowledge; for some, with consciousness of the idol, until now eat it as a thing offered to an idol; and their conscience, being weak, is defiled. 8 But food does not commend us to God; for neither if we eat are we the better, nor if we do not eat are we the worse.

9 But beware lest somehow this liberty of yours become a stumbling block to those who are weak. 10 For if anyone sees you who have knowledge eating in an idol’s temple, will not the conscience of him who is weak be emboldened to eat those things offered to idols? 11 And because of your knowledge shall the weak brother perish, for whom Christ died? 12 But when you thus sin against the brethren, and wound their weak conscience, you sin against Christ. 13 Therefore, if food makes my brother stumble, I will never again eat meat, lest I make my brother stumble."
