Canons of Dort 43

Study of the Canons of Dort, 1618-1619. 5th Head of Doctrine; Article 10: The Assurance of This Preservation-
This assurance, however, is not produced by any peculiar revelation contrary to, or independent of the Word of God; but springs from faith in God's promises, which He has most abundantly revealed in His Word for our comfort; from the testimony of the Holy Spirit witnessing with our spirit that we are children and heirs of God (Rom. 8:16); and lastly, from a serious and holy desire to preserve a good conscience and to perform good works. And if the elect of God were deprived of this solid comfort that they shall finally obtain the victory and of this infallible pledge or earnest of eternal glory, they would be of all men the most miserable.
