Teach Us to Pray

“Some of the psalms of praise are very short, others very long, to teach us that, in our devotions, we should be more observant how our hearts work than how the time passes and neither overstretch ourselves by coveting to be long nor over-stint ourselves by coveting to be short, but either the one or the other as we find in our hearts to pray.” -- Matthew Henry, from his commentary on Psalm 105
