(31) And they said, Believe on the Lord Jesus Christ.--The plural pronoun is not without significance. St. Paul was not the only teacher. Silvanus also took part in the work of conversion. The words have naturally become, as it were, the crucial instance--standing nearly on the same level as that of the penitent robber on the cross--of the conditions of salvation. To believe in Christ, with all that this faith involved, was to obtain salvation, i.e., deliverance from sin, and not only from the penalty of sin, in this world and in the world to come. The Greek presents a contrast which is lost in the English. He had called them by the usual title of respect, Kyrii (= Sirs, or Lords); they answer that there is one Kyrios, the Lord Jesus Christ, who alone can save.

Verse 31. - Jesus for Jesus Christ, A.V. and T.R.; thou and thy house for and thy house, A.V.

16:25-34 The consolations of God to his suffering servants are neither few nor small. How much more happy are true Christians than their prosperous enemies! As in the dark, so out of the depths, we may cry unto God. No place, no time is amiss for prayer, if the heart be lifted up to God. No trouble, however grievous, should hinder us from praise. Christianity proves itself to be of God, in that it obliges us to be just to our own lives. Paul cried aloud to make the jailer hear, and to make him heed, saying, Do thyself no harm. All the cautions of the word of God against sin, and all appearances of it, and approaches to it, have this tendency. Man, woman, do not ruin thyself; hurt not thyself, and then none else can hurt thee; do not sin, for nothing but that can hurt thee. Even as to the body, we are cautioned against the sins which do harm to that. Converting grace changes people's language of and to good people and good ministers. How serious the jailer's inquiry! His salvation becomes his great concern; that lies nearest his heart, which before was furthest from his thoughts. It is his own precious soul that he is concerned about. Those who are thoroughly convinced of sin, and truly concerned about their salvation, will give themselves up to Christ. Here is the sum of the whole gospel, the covenant of grace in a few words; Believe in the Lord Jesus Christ, and thou shalt be saved, and thy house. The Lord so blessed the word, that the jailer was at once softened and humbled. He treated them with kindness and compassion, and, professing faith in Christ, was baptized in that name, with his family. The Spirit of grace worked such a strong faith in them, as did away further doubt; and Paul and Silas knew by the Spirit, that a work of God was wrought in them. When sinners are thus converted, they will love and honour those whom they before despised and hated, and will seek to lessen the suffering they before desired to increase. When the fruits of faith begin to appear, terrors will be followed by confidence and joy in God.And they said, believe in the Lord Jesus Christ,.... Not with a bare historical faith, as only to believe that he was the Son of God, and the Messiah, and that he was come in the flesh, and had suffered, and died, and rose again, and was now in heaven at the right hand of God, and would come again to judge both quick and dead, for there may be such a faith and no salvation; but so as to look unto him alone for life and salvation, to rely upon him, and trust in him; to commit himself, and the care of his immortal soul unto him, and to expect peace, pardon, righteousness, and eternal life from him; the answer is much the same our Lord returned to the Jews, when they asked, though not with the same affection and sincerity as this man, what they must do to work the works of God, John 6:28.

And thou shalt be saved; from sin, and all its miserable effects and consequences; from the curses of the law, from the power of Satan, from the evil of the world, from the wrath of God, hell and damnation: this is to be understood of a spiritual and eternal salvation; for it is said, after that the jailer was inquiring about it, being terrified in his conscience with a sense of sin and wrath; and between believing in Christ, and being saved with an everlasting salvation, there is a strict and inseparable connection, Mark 16:16 though not faith, but Christ is the cause and author of salvation; faith spies salvation in Christ, goes to him for it, receives it from him, and believes unto it:

and thy house; or family, provided they believe in Christ also, as they did, Acts 16:34 or otherwise there can be no salvation, for he that believeth not shall be damned.
