31 They said, "Believe in the Lord Jesus Christ, and you will be saved, you and your household."

Believe in the Lord Jesus. This is but a short, and, to look to, a cold and hungry definition of salvation, and yet it is perfect to believe in Christ. For Christ alone hath all the parts of blessedness and eternal life included in him, which he offereth to us by the gospel; and by faith we receive them, as I have declared, (Acts 15:9.) And here we must note two things; first, that Christ is the mark [1] whereat faith must aim; and, therefore, men's minds do nothing else but wander when they turn aside from him. Therefore, no marvel if all the divinity of Popery be nothing else but an huge lump [2] and horrible labyrinth; because, neglecting Christ, they flatter themselves in vain and frivolous speculations. Secondly, we must note, that after we have embraced Christ by faith, that alone is sufficient to salvation. But the latter member, which Luke addeth by and by, doth better express the nature of faith, Paul and Silas command the keeper of the prison to believe in the Son of God. Do they precisely stay in this voice [word] only? Yea, it followeth in Luke, in the text, [context,] that they preached the word of the Lord. Therefore, we see how the faith is not a light or dry opinion concerning unknown things, but a plain and distinct knowledge of Christ conceived out of the gospel. Again, if the preaching of the gospel be absent, there shall no faith remain any longer. To conclude, Luke coupleth faith with preaching and doctrine; and after that he hath briefly spoke of faith, he doth, by way of exposition, show the true and lawful way of believing. Therefore, instead of that invention of entangled faith, whereof the Papists babble, let us hold faith unfolded in the word of God, that it may unfold to us the power of Christ.

Believe on the Lord Jesus Christ - This was a simple, a plain, and an effectual direction. They did not direct him to use the means of grace, to pray, or to continue to seek for salvation. They did not advise him to delay, or to wait for the mercy of God. They told him to believe at once; to commit his agitated, and guilty, and troubled spirit to the Saviour, with the assurance that he should find peace. They presumed that he would understand what it was to believe, and they commanded him to do the thing. And this was the uniform direction which the early preachers gave to those inquiring the way to life. See the notes on Matthew 16:16. Compare the notes on Acts 8:22.
And thy house - And thy family. That is, the same salvation is equally adapted to, and offered to your family. It does not mean that his family would be saved simply by his believing, but that the offers had reference to them as well as to himself; that they might be saved as well as he. His attention was thus called at once, as every man's should be, to his family. He was reminded that they needed salvation, and he was presented with the assurance that they might unite with him in the peace and joy of redeeming mercy. Compare the notes on Acts 2:39. It may be implied here that the faith of a father may be expected to be the means of the salvation of his family. It often is so in fact; but the direct meaning is, that salvation was offered to his family as well as himself, implying that if they believed they should also be saved.
Believe on the Lord Jesus - Receive the religion of Christ, which we preach, and let thy household also receive it, and ye shall be all placed in the sure way to final salvation.
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.
Believe on the Lord Jesus Christ, and thou shalt be saved--The brevity, simplicity, and directness of this reply are, in the circumstances, singularly beautiful. Enough at that moment to have his faith directed simply to the Saviour, with the assurance that this would bring to his soul the needed and sought salvation--the how being a matter for after teaching.
thou shalt be saved, and thy house--(See on Luke 19:10).
Thou shalt be saved and thy household - If ye believe. They did so, and were saved.
