What does the Bible say about going to a party where strippers will be dancing?
The Bible does not say anything directly about attending a party where strippers will be dancing. If an individual knows without a doubt that they would not be tempted by lust at such a party, then there might be justification for attendance under certain circumstances. For instance, if the individual is a close friend of the guest of honor, making an appearance at the party would not in itself be wrong. It might be best to leave as soon as socially acceptable, though.
On the other hand, the Bible does talk about some of the activities that normally occur at a party that would include a stripper as entertainment. Galatians 5:19-21 says, "Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, 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." If an individual would be tempted by any of these things, then they should avoid the party. A Christian should not appear to condone drunkenness or carousing, or any of these other things.
Maybe one could participate in such a party without sin, but his or her example may cause another to sin. If another, who can not resist the temptations, were to say, "if he can do it, I can do it" and then succumb to temptation, then the stronger person may be, in part, responsible for the weaker person's sin. Romans 14:13-17 talks about eating meat, but the principle of not doing anything that might lead another to sin is valid in many situations, including this. "Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way. I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean. But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died. Let not then your good be evil spoken of: For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost."
Even if it would not be, in and of itself, a sin, the Bible indicates that it might be best not to participate. Another option might be to make an appearance, but make it a point to leave before the "entertainment" begins.
