Faith
It is a suspicious and unsound faith that never trembled at attempting to believe. There is reason to consider that faith not to be of the right stamp, that never walked under the impression of the great distance between Christ and the person, the sense whereof is the thing that makes the trembling—I say not desperation, nor any utter distrust of Christ’s kindness, but trembling—arising from the consideration of the great distance and disproportion that is between Him and the person. Faith causes the sinner to go to Christ, and the sense of his own sinfullness and worthlessness keeps him under holy fear and in the exercise of humility. Paul once thought himself a brave man (as we may see in Romans 7:9), but when he was brought to believe in Christ, he sees that he was a dead and undone man before.
