As if our apostle had said, though in our heathenish and unconverted state we were as bad and vile as any, yet no sooner did the loving-kindness of God to fallen man appear, by the illumination of the gospel, and the communication of his grace, not for any good works or deserts of ours, but of his mere mercy and free goodness, he saved us from that state of sin and misery by regeneration, signified and sealed in baptism, and by renewing of the Holy Ghost, which Holy Spirit was poured forth in an extraordinary measure upon us (according to promise) after Christ's resurrection.
Here observe, How every person in the Trinity acts distinctly in the work of our salvation;
1. The fontal cause, the spring and source of our happiness, lies in the kindness and love of God the Father.
2. The meritorious and procuring cause of the application of this love, is Jesus Christ, in the work of redemption and mediation.
3. The immediate and efficient cause of the communication of that love of God the Father, procured through the mediation of Christ the Son, is the Holy Spirit in the work of regeneration.
