Paul's answer is blessedly short and clear. Its brevity and decisive plainness are the glory of the Gospel. It crystallises into a short sentence the essential directory for all men.
See how little it takes to secure salvation. But see how much it takes; for the hardest thing of all is to be content to accept it as a gift, 'without money and without price.' Many people have listened to sermons all their lives, and still have no clear understanding of the way of salvation. Alas that so often the divine simplicity and brevity of Paul's answer are darkened by a multitude of irrelevant words and explanations which explain nothing!
The passage ends with the blessing which we may all receive. Of course the career begun then had to be continued by repeated acts of faith, and by growing knowledge and obedience. The incipient salvation is very incomplete, but very real. There is no reason to doubt that, for some characters, the only way of becoming Christians is to become so by one dead-lift of resolution. Some things are best done slowly; some things best quickly. One swift blow makes a cleaner fracture than filing or sawing. The light comes into some lives like sunshine in northern latitudes, with long dawn and slowly growing brightness; but in some the sun leaps into the sky in a moment, as in the tropics. What matter how long it takes to rise, if it does rise, and climb to the zenith?
'He brought them out, and said, Sirs, what must I do to be saved? 31. And they said, Believe on the Lord Jesus Christ, and thou shall be saved.'--ACTS xvi. 30, 31.
The keeper of a Macedonian jail was not likely to be a very nervous or susceptible person. And so the extraordinary state of agitation and panic into which this rough jailer was cast needs some kind of explanation. There had been, as you will all remember, an earthquake of a strange kind, for it not only opened the prison doors, but shook the prisoner's chains off. The doors being opened, there was on the part of the jailer, who probably ought not to have been asleep, a very natural fear that his charge had escaped.
So he was ready, with that sad willingness for suicide which marked his age, to cast himself on his sword, when Paul encouraged him.
That fear then was past; what was he afraid of now? He knew the prisoners were all safe; why should he have come pale and trembling? Perhaps we shall find an answer to the question in another one. Why should he have gone to Paul and Silas, his two prisoners, for an anodyne to his fears?
The answer to that may possibly be found in remembering that for many days before this a singular thing had happened. Up and down the streets of Philippi a woman possessed with 'a spirit of divination' had gone at the heels of these two men, proclaiming in such a way as to disturb them: 'These are the servants of the Most High God, which show unto us the way of salvation.' It was a new word and a new idea in Philippi or in Macedonia. This jailer had got it into his mind that these two men had in their hands a good which he only dimly understood. The panic caused by the earthquake deepened into a consciousness of some supernatural atmosphere about him, and stirred in his rude nature unwonted aspirations and terrors other than he had known, which cast him at Paul's feet with this strange question.
Now do you think that the jailer's question was a piece of foolish superstition? I daresay some of you do, or some of you may suppose too that it was one very unnecessary for him or anybody to ask. So I wish now, in a very few words, to deal with these three points--the question that we should all ask, the answer that we may all take, the blessing that we may all have.
