In A Quest for Godliness (p35), J.I. Packer identifies a breed of evangelical Christians as ‘restless experientialists’.

Their outlook is one of casual haphazardness and fretful impatience, of grasping after novelties, entertainments, and ‘highs’, and of valuing strong feelings above deep thoughts. They have little taste for solid study, humble self-examination, disciplined meditation, and unspectacular hard work in their callings and their prayers. They conceive the Christian life as one of exciting extraordinary experiences rather than of resolute rational righteousness. They dwell continually on the themes of joy, peace, happiness, satisfaction and rest of soul with no balancing reference to the divine discontent of Romans 7, the fight of faith of Psalm 73, or the ‘lows’ of Psalms 42, 88 and 102. Through their influence the spontaneous jollity of the simple extrovert comes to be equated with healthy Christian living, while saints of less sanguine and more complex temperament get driven almost to distraction because they cannot bubble over in the prescribed manner. In their restlessness these exuberant ones become uncritically credulous, reasoning that the more odd and striking an experience the more divine, supernatural, and spiritual it must be, and they scarcely give the scriptural virtue of steadiness a thought.

What, asks Packer, have the Puritans to says to such Christians?

First, the stress on God-centredness as a divine requirement that is central to the discipline of self-denial.

Second, the insistence on the primacy of the mind, and on the impossibility of obeying biblical truth that one has not yet understood.

Third, the demand for humility, patience, and steadiness at all times, and for an acknowledgment that the Holy Spirit’s main ministry is not to give thrills but to create in us Christlike character.

Fourth, the recognition that feelings go up and down, and that God frequently tries us by leading us through wastes of emotional flatness.

Fifth, the singling out of worship as life’s primary activity.

Sixth, the stress on our need of regular self-examination by Scripture, in terms set by Psalm 139:23–24.

Seventh, the realisation that sanctified suffering bulks large in God’s plan for his children’s growth in grace.
