Charles H. Spurgeon on Psalms 143:5

I meditate. I stretch forth my hands. Meditation is prayer's handmaid to wait on it, both before and after the performance of supplication. It is as the plough before the sower, to prepare the heart for the duty of prayer; and as the harrow after the sower, to cover the seed when 'tis sown. As the hopper feeds the mill with grist, so does meditation supply the heart with matter for prayer. —William Gurnall.
