There is a legend of a man who found the barn where Satan supposedly kept his seeds ready to be sown into the human heart. On finding these seeds of discouragement more numerous than the other seeds, he learned that those seeds could be made to grow almost anywhere.
When Satan was questioned, he reluctantly admitted that there was one place in which he could never get the seeds of discouragement to grow. "Where is that, Lucifer?" he was asked.
Satan paused for a moment and replied sadly, "That would be in the heart of a GRATEFUL man!"
Thankfulness leaves no room for DISCOURAGEMENT.
