Acts 16:31 - Matthew Poole's English Annotations on the Holy Bible

Believe on the Lord Jesus Christ; this is the sum of the gospel. Christ, apprehended by faith, serves for wisdom, righteousness, sanctification, and redemption, as 1 Corinthians 1:30. But then this precious faith must be such as works by love, as purifies the heart, Acts 15:9, as overcometh the world, 1 John 5:4, as quenches the fiery darts of the devil, Ephesians 6:16, and is deservedly called, a most holy faith, Judges 1:20. Thou shalt be saved, and thy house; thou shalt by this means come to obtain that life thou dost so much desire after; and not only thyself, but (God gives more than we ask) thy children and family shall be saved; inasmuch as the covenant, where it is entered into, is not only with them, but with their children.
