That being said, topcat is right. We have an obligation to preach and teach the word accurately. I think it was Charles Spurgeon who stated something to the effect that he would preach as an Arminian but teach as a Calvinist. It is one thing to present the message of Christ so that people will respond to the hearing of the gospel, but it is quite another to teach them about regeneration contrary to God's word.
I've been involved with a number of the groups you've mentioned in time, effort and support. My wife, for a while, was on the ministry staff of one of these groups. In most cases they are very fine organizations. But their bible studies usually contain questions like:
"Read Amos 1:4-7. How can you apply this to your life?"
