If you would truly profit by ordinances, after you have a fixed pastor, I think it is of moment to forget, as much as possible, the persons of men, and confider them as no more than instruments in the hand of God, for your daily instruction and comfort. The more you remember the appointment of God, and wait upon his ordinances, in the faith of his presence, and the expectation of his blessing, the more you are likely to receive both sensible and lasting benefit. I must therefore take the liberty to observe, that we have amongst us a set of wandering unsettled hearers, who run about from one congregation to another, and even from one profession to another, and are scarcely ever to be seen a whole day in one place. If they be but deliberating where to fix, we may fay of them, that they are ever learning, and never come to the knowledge of the truth. But the probability is, that they have itching and curious ears, and go about not to serve God but to hear men. If I am able at all to judge, either by reflection or observation, those are most likely to profit, who having deliberately made their choice, sit habitually and regularly under one minister. By this means they enter into his views; and as he will naturally endeavour, if any thing was wanting at one time, to complete his scheme by supplying it at another, they will thereby have a more comprehensive view of the whole counsel of God. At the fame time, not having the charm of novelty to enchant them, they will have nothing to do but to reap instruction. On the other hand, by hearing separate, detached, and independent discourses, men may please their fancy more, but they will improve their understanding less. It is also plain, that as every minister will endeavour, not only to follow an order in his discourses on one subject, but to have a respect to the connection, and relation of the subjects themselves, the more accurate and exact he is, in suiting one part to the, illustration of another, the less he will be understood by these desultory hearers, who take only a single branch, without being able to perceive its subserviency to the general design. I have many times known exceptions taken at ministers, for some parts of a discourse by such persons, when, if they had heard the whole upon the fame or corresponding subjects, they would have perceived there was no place for their objections. The great purpose, my brethren, of a serious and judicious people, in attending on ordinances, should neither be to please themselves, nor to criticise their teachers; but to hear the word of God, that they may do it. On this account it is, that humble and regular Christians are getting real advantage to their fouls, while some are only watching the opinions, or others only passing judgment on the ability, perhaps no more than the style and outward manner of the speaker.
“No person can be a child of God without living in secret prayer; and no community of Christians can be in a lively condition without unity in prayer. In Daniel’s time you see how it was. (Dan. ii. 17, 18.) You see what Jesus said to his disciples on it (Mat. xviii. 19), and what a sweet promise of his presence and a gracious answer he connects with meeting for prayer. You see how it will be in the latter day (Zech. vii. 21), when meetings for prayer, or, at least, concerts for prayer, shall be held by different towns. One great rule in holding them is, that they be really meetings of disciples. If four or five of you, that know the Lord, would meet together regularly, you will find that far more profitable than a meeting open to all. In an open meeting you are apt to become teachers, and to be proud. In a secret meeting you feel all on a level, poor and needy, seeking water. If a young man, acquainted with any of you, becomes concerned about his soul, or a lively Christian is visiting any of you, these may be admitted; but do not make your meeting more open. 
“And if he had not been man, how could he have led us into the way of universal holiness, by the influence of his own example, which is, doubtless, an excellent method to reform mankind? It is not only necessary to enact rules of virtue by a kingly authority,but likewise, by example, to make precepts practicable and honourable. When brave generals, though of the noblest lineage, design to animate their armies to heroic achievements, they voluntarily submit their persons to all the humble offices and hardships of a state of war, courageously lead their troops into the high places of the field of battle,and expose their lives to the greatest perils. This our Lord has done for us; the Captain of our salvation, the King of the church, and Lord of the universe, has been made perfect through sufferings.”
“And there is another promise, ‘He is their strength in the time of trouble‘ (Psalm 37:39). ‘Oh,’ says the soul, ‘I shall faint in the day of trial.’ But God will be the strength of our hearts; He will join His forces with us. Either He will make his hand lighter, or our faith stronger.”
