"What is our greatest hindrance in worshipping God? We could come up with a number of potential answers.
“Our worship leader isn’t very experienced.”
“The services are too planned/spontaneous.”
“The songs are too complex/simple.”
“The band/orchestra/organist/guitarist sounds bad.”
“There are too many new/old songs.”
“Our church is too big/small.”
Ignoring for a moment that all these statements refer to a meeting context, they reveal a profound misconception about the hindrances to true worship. Contrary to what we might think, our greatest problem doesn’t lie outside us, but within our own hearts. It’s the problem of idolatry."
