Anyone unwilling to do whatever God asks won't be much use to the Lord in whatever situation he finds himself. I'm willing to do what God wants, but right now I simply don't feel as though I could ever raise support. Let's face it, raising support is uncharted ground for most of us. In the back of our minds, we fear that as missionaries who raise support we will be financially insecure and we'll put our families in jeopardy. The truth is that at times we will.
Some people feel that raising support is tantamount to accepting Christian welfare.
Yet the Bible strongly states that this is part of God's economy, His way of financing the spread of the gospel. Financial independence is the goal. The real problem with raising support, then, is not that it's at odds with any practice in the Bible.
