Weakness with watchfulness will stand, when strength with too much confidence fails. Weakness, with acknowledgement of it, is the fittest seat and subject for God to perfect his strength in; for consciousness of our infirmities drives us out of ourselves to him in whom our strength lies.
The Bruised Reed
I say there are two courts: one of justification, another of sanctification. In the court of justification merits are nothing worth, insufficient; but in the court of sanctification, as they are ensigns of a sanctified course, so they are jewels and ornaments.Complete Works (Edinburgh: James Nichol, 5:85)
