“A mind on wheels knows no rest; it is as a rolling thing before the tempest. Struggle against the desire for novelty, or it will lead you astray as the will-o’-wisp deceives the traveler. If you desire to be useful, if you long to honor God, if you wish to be happy, be established in the truth, and be not carried about by every wind of doctrine in these evil days, ‘be ye steadfast, unmovable’ (Spurgeon’s Sermon Illustrations, 78).

Right. And a will-o’-wisp is this.
