From the Heart by B.Demaere

Hearing this, a man sitting at the table with Jesus exclaimed, "What a privilege it would be to have a share in the Kingdom of God!" Jesus replied with this illustration: "A man prepared a great feast and sent out many invitation.  When all was ready. he sent his servant around to notify the guests that it was time for them to come.  But they all began making excuses.  One said he had just bought a field and wanted to inspect it, so he asked to be excused.  Another said he just had bought five pair of oxen and wanted to try them out.  Another had just been married, so he said he couldn't come.

Jesus said, "How can I describe the Kingdom of God?  What story should I use to illustrate it?  It is like  a mustard seed planted in the ground.  It is the smallest of all seeds, but it becomes the largest of all garden plants; it grows long branches and birds can make nests in its shade."
