FELIX Neff once made the following comparison: — “When a pump is frequently used, but little pains are necessary to have water; the water pours out at the first stroke, because it is high. But if the pump has not been used for a long while, the water gets low, and when you want it you must pump a long while, and the water comes only after great efforts. It is so with prayer; if we are instant in prayer, every little circumstance awakens the disposition to pray, and desires and words are always ready. But if we neglect prayer it is difficult for us to pray; for the water in the well gets low.”
