There is provision in the covenant of grace against peace-ruining, soul-perplexing sins, is not, as to the administration of it, absolute. There are covenant commands and exhortations, on the attendance whereunto the administration of much covenant grace doth depend. To watch, pray, improve faith, to stand on our guard continually, to mortify sin, to fight against temptations, with steadfastness, diligence, constancy, are everywhere prescribed unto us; and that in order unto the insurance of the grace mentioned.
