The Holy Spirit can be "grieved" and the flame of the Spirit can be "extinguished" (Eph. 4:40; 1 Thess. 5:19).
And the line between honest doubt and sinful irritation and disillusionment with God can be elusive. Consider Jesus' question about counterfeit spirituality: "Are grapes gathered from thorns, or figs from thistles (Matthew 7:26)?" Jesus probably had in mind "the buckthorn which had little black berries that closely resembled little grapes," and "a certain thistle, which had a flower, which at least at a distance, might well be taken for a fig (quoting William Barclay's Commentary)." The saying is thus reminiscent of a saying of Jesus from oral tradition often quoted by early Church Fathers: "Jesus said: Be wise money-changers; throw away the bad (coins); keep the good (coins)." The Jewish money-changer's job included not only foreign exchange of currency, but an examination of coins to detect counterfeits. A discerning eye might detect a slight change in color, line thickness, or shape of imagery that gives away the counterfeit. Jesus' point would then be the difficulty of discerning the difference between true and false spirituality, a difficulty that reinforces His prior point about the danger of premature self-assessment or judgment of others.
Matthew adds this teaching in his discussion of these sayings:
"Not everyone who says to me, "Lord, Lord" will enter the kingdom of heaven, but only the one who does the will of my Father in heaven. On that day many
will say to me, "Lord, Lord, did we not prophecy in your name, and cast out demons in your name, and do many deeds of power in your name?" Then I will declare to them, "I never knew you; go away from me... (Matthew 7:21-23)!"
Jesus' point is that people can have spiritual gifts apparently indicative of saintliness without having the essential intimate personal relationship with Jesus. Since we all occasionally display character flaws and have complex motivation for our service, it is dangerous to presume who does and does not have a mystical bond with Jesus.
