I will make with them an everlasting covenant, that I will not turn away from doing good to them. And I will put the fear of me in their hearts, that they may not turn from me.
~ Jeremiah 32:40
“A question may, however, be here raised: we see that the faithful often stumble, not ten times during life, but every day: how then is this, that where God’s Spirit works, his efficacy is such that men never turn aside from the right way? Were any to answer, that the faithful indeed stumble, but do not wholly fail, and that God here refers to that defection which shakes off every fear of God, it would not be a full solution. For we see that even the elect themselves are sometimes like apostates, for the fear of God and piety are, as it were, choked in them. Piety is not indeed extinguished, but not even a spark of the Spirit appears in them. But we must notice, that inflexible perseverance is given to the faithful, so that when they fall, they soon repent.”
~ John Calvin
