"The problem is, I think, that, as human beings, we know our limitations. Or at least, we think we do. There are certain things we’ve never done before, and so we assume that such things, whatever they may be, are not part of what God expects for us. If you’ve never led a children’s Sunday school class or shared your faith in Christ with a neighbor or colleague at work, you might assume that these are not things you should endeavor. Someone else, better prepared and with more experience, will have to take up these callings.
But if the Spirit of God lives in us, and if He is, indeed, able to do far more abundantly than all we ask or think, should we not expect more of ourselves than merely what we’ve ever known or endeavored in the past? Shall we be limited by our experience when an exceeding abundant power is at work within us?
If you’re beginning to feel stretched to the limits of what you might be able to learn or do in advancing the divine economy, then there’s a simple solution: Stop relying only on your experience and present abilities, and begin stretching out into the vast resources of the Spirit of God!"
~ T.M. Moore, from article Stretch out in the Spirit
