Paul weighed in on the secular/sacred divide:
1 Corinthians 10:31 (NLT)
. . . whatever you do, do it all for the glory of God.
Be careful, you say, about the context. And you’re right. We don’t want to distort Paul’s message. And this particular context is involves eating meat that has been offered to idols, a topic well outside my personal experience.
But if eating meat sacrificed to idols can be done for the glory of God, most of the stuff within my experience can be done for God’s glory too.
