A person on whom an emperor was about to bestow a valuable present, declined the gift on the ground that it was too costly for his acceptance.
"But not too costly for an emperor to give," was the reply.
None of us are really worthy of the gifts of God— especially of His one "Unspeakable Gift." Blessedly they are not bestowed according to our merit, but rather by His ability to give. And it pleases God to accept meager thanks as their full acknowledgment.
