First. I shall show why the Christian is to watch unto prayer.
- Reason. Because of the importance of the duty of prayer. No one action doth a Christian meet with in his whole life of greater weight and moment than this of prayer is; and that in regard of God or himself.
(1.) In regard of God. Prayer is an act of religious worship; we have immediately to do with the great God, to whom we approach in prayer. Now religion is as tender as the eye; it is not a thing to be played with or handled without great care and heedfulness. Prayer is too sacred a duty to be performed between sleeping and waking, with a heavy eye or a drowsy heart. This God complained of, ‘There is none that calleth upon thy name, that stirreth up himself to take hold of me,’ Isa. 64:7. He counts it no prayer where the heart is not stirred up and awake. No way can we more honour or dishonour God than in prayer. O how then ought we to watch to this duty!
(2.) Again, in regard of ourselves; for our behaviour in prayer hath a universal influence into all the passages of our whole life. As a man is in this duty so he likely to be in all the rest. If careless in praying, then slighty in hearing, loose in his walking; he shall find that he miscarries in all his enterprises, is ensnared in all his enjoyments, baffled with every temptation, and discomposed at every affliction that meets him. And the reason of all this is—because our strength both to do and suffer comes from God. Now God communicates his assistance to his children in a way of communion with them. They ask, and they have; they seek, and find; knock, and the treasury of mercy is opened to them. Prayer is the channel in which the stream of divine grace, blessing, and comfort runs from God the fountain into the cistern of their hearts. Dam up the channel and the stream is stopped. If the stomach doth not its office all the members want their nourishment. If the trade fails in the shop there is but a poor house kept within.
- Reason. Watchfulness is of as great importance to prayer as prayer is to all our other duties. No duty can be despatched well without prayer, nor prayer without watching; for it is not prayer, but prayer performed in a holy spiritual manner, that is effectual. Now, this cannot be done when the is off his watch. Take the Christian a napping, with his grace in a slumber, and he is no fitter to pray than a man is to work that is asleep. Whatever a man is doing, sleep, when it comes, puts an end to it. Sleep is the great leveller of the world, it makes all men alike. The strong man is as unable to defend himself from an enemy in his sleep as the child. The rich man asleep and the poor man are alike; he enjoys his estate no more than if he had none. Thus the Christian, while his graces are asleep, is even like another that hath no grace—as to the present use of them, I mean—he will pray as the carnal man doth, enjoy God no more in the duty than such a one would do. O how sad is this! and yet how prone are we to give way unto this drowsiness of spirit in prayer! It creeps insensibly upon the soul, as sleep doth upon the body; the heart is gone before the Christian is well aware. The more need therefore there is to watch against it.
3. Reason. Because Satan is so watchful against prayer, therefore it behoves the Christian to watch unto prayer. Where should the strongest guard be set but where the enemy maketh his fiercest assault? This is the fort he batters and labours with all his might to beat the Christian from, well knowing the shot which gall him most come out of it. What he doth otherwise against the Christian is on a design to hinder his prayers, I Peter 3:7, as an enemy falls upon one part of the city to draw their forces from another place which he chiefly desires to gain. Indeed the soul never falls fully into his hands till it throws up this duty. ‘Pray that ye enter not into temptation.’ Sometimes the city is taken, and the enemy is forced back again, by those in the castle which commands the city. Prayer is like such a castle. Sometimes the Christian hath nothing left him but a spirit of prayer, and with this he beats back the devil out of all his advantages, and wrings out of his hands his new-gotten victories.
