Luke 11:9 (KJV) And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.
It is said that on one occasion when Caesar gave a very valuable present, the receiver replied that it was too costly a gift. The Emperor answered that it was not too great for Caesar to give. Our God is a great King, and He delights to give gifts to us: so let us delight to ask Him for great things.
