Paragraph 18.2
Of the Second London Baptist Confession of Faith
This Certainty is not a bare conjectural and probable Persuasion, grounded upon a fallible Hope, but an infallible Assurance of Faith, founded on the Blood and Righteousness of Christ1 revealed in the Gospel; and also upon the inward2 evidence of those Graces of the Spirit unto which Promises are made, and on the Testimony of the3 Spirit of Adoption, witnessing with our Spirits, that we are the Children of God; and, as a Fruit thereof, keeping the Heart both4 humble and holy.5
The Westminster Confession of Faith (1646)
18.2
This certainty is not a bare conjectural and probable persuasion, grounded upon a fallible hope;1 but, an infallible assurance of faith, founded, upon the divine truth of the promises of salvation,2 the inward evidence of those graces unto which these promises are made,3 the testimony of the Spirit of Adoption witnessing with our spirits that we are the children of God:4 which Spirit is the earnest of our inheritance, whereby we are sealed to the day of redemption.5
