Christians going to nightclubs?

Should Christians visit nightclubs? Isn’t that a matter of Christian liberty?

I assume you mean going to a nightclub with the intention of more or less participating in its normal activities, or at least endorsing them by your presence, rather than some kind of (perhaps misguided) evangelistic effort.

I am concerned about the ‘angle’ of the question. Christian liberty is not a question of how far we can push our privileges without sliding into sin. Christians are liberated to pursue holiness in the fear of the Lord. We are set free from sin’s enticements and enslavements, set apart to God, called to be holy as he is holy (1 Peter 1:16). Questions that seem to ask, ‘How far can I go without sinning?’ are coming from the wrong angle.
