We've misinterpreted the Great Commission, I think.
We're called to introduce people to Jesus, but sometimes it seems that sometimes we forget. Sometimes, we end up introducing them to our club, to churchianity. To religion. Ewww.
They're looking for real relationship, and Jesus offering real relationship, but we're offering membership in a Sunday Morning Club complete with its own foreign language and foreign culture. "Bring your friends to church!" we are exhorted, forgetting the "Go" of the Great Commission.
Coming to faith does NOT require leaving your culture, leaving your language, leaving your community, leaving your music behind. (Yes, it does involve leaving your slavery behind.) For example, there's no need for a pipe organ or Taylor acoustic guiter in a tribal church in order for their gathering to be legit. They worship with drums; you don't have to!
Here's a radical thought: Christian pop music is by NO means the only music that's acceptable - or desirable. Some believers like barbershop quartets! Others touch God in metal music or Dixieland or Baroque or dance music.
I even know of a church that worshiped with (shudder!) country music! They would line dance in church! What?!? (And they shared the building with a church that worshiped with grunge rock music! What's up with that?)
I get it that some folks often can't go back to the culture that enslaved them for years, but let's distinguish between the slavery that held us captive and the preference of music the enslavers enjoyed while they practiced their torture upon our souls.
And since music reaches people, the Great commission applies to music: GO TO THEM. Do NOT expect them to come to you. So bring the gospel to their music; not Gospel music, but the "Good News" of the Kingdom: that belongs in THEIR music, too. There's no need for them to leave their love for Italian operas behind in order to meet Jesus.
Our commission is to go to them, and to bring the good news of the Kingdom to them.
Our job is NOT to bring them to our culture, our little club.
When we disciple folks, we are to make them followers of Jesus, not into MiniMe's.
