I have been told not to admire "mere mortals" like The Beatles. Doesn't the Bible say that we are all mere mortals and not divine? I believe in rendering credit where credit is due, respect to whom it is due, honor to whom it is due, fear to whom it is due (Fear God, honor the emperor), accolades to whom due, et cetera. All music is a gift of God and James 1:17 says that "every good gift" is "from above."
This kind of logic (to avoid secular music) is erroneous. Why? Isn't most classical music composed by unbelievers also? Yet these same Christians are not on the bandwagon to abolish classical music. Whitney Houston was a Christian (just listen to her sing "Jesus Loves Me") and she sang R & B. Now, take The Beatles, for instance: Most of their music is innocent love songs and fun to sing along with--what is wrong with that? Elvis won his only two Emmys with gospel music!
We must show some discernment but to judge a whole genre of music is out of line and too critical. Music is not evil per se, but sometimes lyrics can be a bad influence. Believers are at different stages of growth and we cannot be intolerant of one another's taste in music--there is no one-size-fits-all genre. Soli Deo Gloria!
