All the lessons learned in God's school of prayer made Mr. Muller's feelings and convictions about this matter more profound and subduing. He saw the vital relation of prayer to holiness, and perpetually sought to impress it upon both his hearers and readers; and, remembering that for the purpose of persuasion the most effective figure of speech is _repetition,_ he hesitated at no frequency of restatement by which such truths might find root in the minds and hearts of others.
There has never been a saint, from Abel's day to our own, who has not been taught the same essential lessons. All prayer which has ever brought down blessing has prevailed by the same law of success--_the inward impulse of God's Holy Spirit._ If, therefore, that Spirit's teachings be disregarded or disobeyed, or His inward movings be hindered, in just such measure will prayer become formal or be altogether abandoned. Sin, consciously indulged, or duty, knowingly neglected, makes supplication an offence to God.
Again, all prayer prevails only in the measure of our real, even if not conscious, unity with the Lord Jesus Christ as the ground of our approach, and in the degree of our dependence on Him as the medium of our access to God.
Yet again, all prayer prevails only as it is offered in faith; and the _answer_ to such prayer can be recognized and received only _on the plane of faith;_ that is, we must maintain the believing frame, expecting the blessing, and being ready to receive it in God's way and time and form, and not our own.
The faith that thus _expects_ cannot be surprised at answers to prayer. When, in November, 1840, a sister gave ten pounds for the orphans, and at a time specially opportune, Mr. Muller records his triumphant joy in God as exceeding and defying all expression. Yet he was _free from excitement and not in the least surprised,_ because by grace he had been trustfully waiting on God for deliverance. Help had been so long delayed that in one of the houses there was no bread, and in none of them any milk or any money to buy either. It was only a few minutes before the milkman's cart was due, that this money came.
However faithful and trustful in prayer, it behooves us to be none the less careful and diligent in the use of all proper means. Here again Mr. Muller's whole life is a lesson to other believers. For example, when travelling in other lands, or helping other brethren on their way, he besought the Lord's constant guardianship over the conveyances used, and even over the luggage so liable to go astray. But he himself looked carefully to the seaworthiness of the vessel he was to sail in, and to every other condition of safe and speedy transportation for himself and others. In one case where certain German brethren and sisters were departing for foreign shores, he noticed the manner in which the cabman stored away the small luggage in the fly; and observed that several carpetbags were hastily thrust into a hind boot. He also carefully counted the pieces of luggage and took note of the fact that there were seventeen in all. On arriving at the wharf, where there is generally much hurry and flurry, the dishonest cabman would have driven off with a large part of the property belonging to the party, but for this man of God who not only _prayed_ but _watched._ He who trusted God implicitly, no less faithfully looked to the cabman's fidelity, who, after he pretended to have delivered all the luggage to the porters, was compelled to open that hind boot and, greatly to his own confusion, deliver up the five or six bags hidden away there. Mr. Muller adds in his Narrative that "such a circumstance should teach one to make the very smallest affairs a subject of prayer, as, for instance, that all the luggage might be safely taken out of a fly." May we not add that such a circumstance teaches us that companion lesson, quite as important in its way, that we are to be watchful as well as prayerful, and see that a dishonest cab-driver does not run off with another's goods!
