On the Desiring God website, there was a great Jonathan Edwards quote from his book "Religious Affections":
"All gracious affections that are a sweet odor to Christ, and that fill the soul of a Christian with a heavenly sweetness and fragrancy, are broken hearted affections. A truly Christian love, either to God or men, is a humble broken hearted love. The desires of the saints, however earnest, are humble desires. Their hope is a humble hope; and their joy, even when it is unspeakable, and full of glory, is a humble broken hearted joy, and leaves the Christian more poor in spirit; and more like a little child, and more disposed to a universal lowliness of behavior."
