Let none be so foolish as to sit down contented without sanctification, but study holiness as ever ye would see heaven. We want a title to heaven, we must get that in justification and adoption: we want a meetness for heaven, and we must get that in sanctification. The sanctified are elected, and shall be glorified, 1 Pet. 1:1, 2, 4. And they that live and die unsanctifled, shall never see heaven, Heb. 12:14. ‘For without holiness no man shall see the Lord.’
- Thomas Boston, Works, vol. 1, 661.
