After this year's Evangelical Ministry Assembly, one of the questions that threw up a bit of discussion was whether we should ask non-Christian musicians to play or sing in our meetings.
I'll be up-front and admit that I am not keen, but the Bible doesn't stipulate either way, so I'm happy to have my opinion changed (actually that's not true - I'm a sensitive artistic type, so I'm prone to take any challenge personally and go all quiet and moody).
Let me put some arguments for and against.
For:
1) We don't discourage non-Christians from singings hymns with us in the congregation. What's the difference in having them sing them standing up front?
