1. A believer is foiled with temptation. Satan gains ground against him by this means, and pursues the victory which the flesh has obtained against the spirit; hereupon his conflicts are doubled, arising not only from _flesh and blood; but the rulers of the darkness of this world_, Eph. vi. 12. as the apostle expresses it: now his difficulties encrease upon him, his enemies are more insulting, and he less able to stand his ground against them, his faith weakened, and his fears encreasing, so that he is perpetually subject to bondage; sometimes inclined to think that he shall one day fall, and whatever he formerly thought he had gained, he lost by the assaults of his spiritual enemies; and at other times, to question whether ever he had the truth of grace or no; in which case his spirit must needs be filled with the greatest perplexity, and almost overwhelmed within him. And he is destitute of that boldness or liberty of access to the throne of grace, and that comfortable sense which once he had of his interest in Christ, and finds it very difficult to recover those lively frames which he has lost, or to stand his ground against the great opposition made by corrupt nature, which still increases as faith grows weaker. 2. Another consequence hereof, is his falling into many sins. By which we are not to suppose that he shall be so far left as to fall into a state of unregeneracy, or lose the principle of grace that was implanted in regeneration: nevertheless, when this principle does not exert itself, and corrupt nature on the other hand, is prevalent, it is hard to say how far he will run into the commission of known and wilful sins. As for sins of infirmity, they cannot be avoided, when we are in the best frame: but in this case we shall find a person committing presumptuous sins, so that if we were to judge of his state by his present frames, without considering the former experiences which he has had of the grace of God, we should be ready to question, whether his heart were right with God.
