Charles Spurgeon Commentary Matthew 6:6-8

"But thou, when thou prayest, enter into thine inner chamber, and having shut thy door, pray to thy Father who is in secret, and thy Father who seeth in secret shall recompense thee. And in praying use not vain repetitions, as the Gentiles do: for they think that they shall be heard for their much speaking. Be not therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him." — Matthew 6:6-8 (ASV)

Pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly. But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him.

Prayers are never measured by the yard in heaven. They are estimated by their weight. If there is earnestness in them, truth, sincerity, God accepts them, however brief they are. Indeed, brevity is often an excellence in prayer. Let us never, therefore, use vain repetitions.
