It is the gospel that speaks to young people and old people. Red and yellow, black or white. All are precious in his sight. There isn't a single style of music today that isn't giving praise to God. That's something to celebrate, not condemn.
Words are neither secular or sacred.
The New Testament was not written in classical Greek, but street language Greek. There are no sacred words in the Bible that weren't also used by pagans throughout the Mediterranean world. It's not the words themselves that are sacred. It's the message that is sacred. It's all about the intent behind the words.
