Acts 18:2

(2) We cannot exclude from the probable motives the strong feeling of thankfulness for deliverance from danger, following upon fear which, as in nearly all phases of the religious life, has been the chief impulse out of which vows have grown. We have seen the fear, and the promise, and the deliverance, in the record of St. Paul’s work at Corinth, and the vow of self-consecration, for a season, to a life of special devotion was the natural result. St. Paul had not learnt to despise or condemn such expressions of devout feeling.
