Matthew 6:8

Be not ye therefore like unto them
. Do not be imitators of them, and follow their ways, who have only the dim light of nature to guide them; it would be shameful in you to do as they do, when you have a divine revelation for your direction; and especially, because

your Father knoweth what things ye have need of before ye ask him;
and therefore have no need to make use of many words, or much speaking, or long prayers. The omniscience of God is a considerable argument, and a great encouragement to prayer; he knows our persons and our wants before hand; and as he is able to help us, we have reason to believe he will; especially since he stands in the relation of a Father to us.
