I’ve had a few people ask me this question this past summer. I even had one brother go as far as to say that he will be bumping Trip Lee on his honeymoon lol! That was too funny! Of course, I discouraged bumping Trip Lee on the honeymoon, but everyone has their preference.
As for me, I believe that the Word of God should be the authority in every area of our lives. While the Word of God doesn’t specifically say listen to “secular music” or not. It does provide general guidelines for our lives such as the below scripture:
The above scripture provides a guideline of how to assess our interaction with things that only pertain to profiting the body, natural man, or the flesh. Secular music is something that primarily appeals to our natural man and there is nothing wrong with that unless the secular music is awakening sin in us. That is a different issue altogether.
There are many things that deal with our natural man that are totally appropriate and beneficial, such as the example mentioned earlier associated with marriage. On a honeymoon type of experience, I would not play any rap. If I did choose to play music, it would definitely be R&B or Jazz. The Bible has no problem with this, it has a benefit. However, it does not have the same benefit of things that awaken or quicken our spiritual man and spiritual appetites.
