From The London Confession, 1644 (a.k.a. First London Baptist Confession)
XXI. That Christ Jesus by his death did bring forth salvation and reconciliation only for the elect, which were those which God the Father gave him; and that the Gospel which is to be preached to all men as the ground of faith, is, that Jesus is the Christ, the Son of the ever blessed God, filled with the perfection of all heavenly and spiritual excellencies, and that salvation is only and alone to be had through the believing in his Name.
XXII. That Faith is the gift of God wrought in the hearts of the elect by the Spirit of God, whereby they come to see, know, and believe the truth of the Scriptures, and not only so, but the excellency of them above all other writings and things in the world, as they hold forth the glory of God in his attributes, the excellency of Christ in his nature and offices, and the power of the fullness of the Spirit in its workings and operations; and thereupon are enabled to cast the weight of their souls upon this truth thus believed.
XXIII. Those that have this precious faith wrought in them by the Spirit, can never finally nor totally fall away; and though many storms and floods do arise and beat against them, yet they shall never be able to take them off that foundation and rock which by faith they are fastened upon, but shall be kept by the power of God to salvation, where they shall enjoy their purchased possession, they being formerly engraven upon the palms of God’s hands.
XXIV. That faith is ordinarily begot by the preaching of the Gospel, or word of Christ, without respect to any power or capacity in the creature, but it is wholly passive, being dead in sins and trespasses, doth believe, and is converted by no less power, than that which raised Christ from the dead.
