Charles H. Spurgeon on Psalms 145:15

Doth not nature teach you to pray? Ask the brutes, the ravens, lions, etc. (Job 38:41 Ps 147:9 104:27 145:15); not as if these unreasonable creatures could know and worship God, but because nature hath taught them so much of this duty as they are capable of and can bear; they have some sense of their burdens and wants, they groan and cry, and desire to be eased; and the Lord hearkeneth to this voice and saith, "Now the poor creature is crying to me, and I will pity it." Ah! shall the beasts in their own way cry to God, and wilt thou be silent? Hath the Lord elevated thee so far above these inferior creatures, and fitted thee for the immediate acts of his worship, and for a higher communion with himself, and wilt thou not serve him accordingly? Hath he given thee a heart and a spiritual soul, as he hath given the brutes a sensitive appetite and natural desires, and shall they cry to God with the one, and not thou with the other? —Alexander Pitcairne, 1664.
