Sin is sovereign till sovereign grace dethrones it.
Conversion is not, as some suppose, a violent opening of the heart by grace, in which will, reason and judgment are all ignored or crushed. The season is not blinded, but enlightened; and the whole man is made to act with a glorious liberty which it never knew till it fell under the restraints of grace.
When our troubles are many we are often by grace made courageous in serving our God; we feel that we have nothing to live for in this world, and we are driven, by hope of the world to come, to exhibit zeal, self-denial, and industry.
