Suffering as an Evidence of Love

When suffering is attended with right affections, it becomes one of the strongest, and perhaps the only satisfactory evidence of true love. If God should bestow upon us mercies alone, without trials, it might be difficult to say, whether we loved him for himself, or only for the blessings he gave. But if our affection remains unshaken under the trials he sees fit to send, we have good reason to regard it as true. The love which exists and flourishes at such times is not a mere accessory, dependent for its continuance upon circumstances, but is a permanent principle.
