Jesus always favored pipe organs.
I didn’t think Joshua was up on the mountain.
Blessings to these musicians. They are reaching teenagers in ways that the youth group at your church (if you even have one) is not.
By the way... if you are in the southern Maryland area, please pray for and check out the SevenThirty Club, which offers this music and witness for area teenagers. I've seen 40 teenagers on their knees, giving their lives to Christ, at events at this club. The 7:30 Club is in Mechanicsville MD.
Joshua waited for Moses during Moses's 40 days on the mountain, and then return with him to the Israelites camp. So he was more "at" the mountain, as opposed to "on" the mountain.
