The safety of appearing at the day of judgement, in the righteousness of Christ

Beware of frowardness and discontent: frowardness ⟨p. 345⟩is one great cause of discouragement and unbelief: men get into a discontented frame, and then they don't know how to believe: their spirits are disordered by the dispensations of God unto them; because God brings great and long afflictions upon them, don't hear their prayers, don't give them those inward comforts that he does unto others, and when their spirits are distempered with discontent, they are greatly disadvantaged to receive the encouragement that God offers unto them: discontent is an enemy unto faith: therefore beware of a discontented spirit; when you are under any rebukes of Providence, look to your spirits, and labour against the first stirrings of a froward spirit; the workings of frowardness does prove a temptation to unbelief, and so do the workings of any other corruption, as the sinfulness thereof does fright a man from believing: but this is not all: a froward spirit leads a man into unbelief: it is a principle and cause of unbelief.
