Doubtful Matters

When we are doubtful as to the character of the temptation, in other words, when we are doubtful whether the proposed action or feeling is wrong or not, we should be careful to lay the subject before God, and to wait for the instructions of the Holy Spirit, before indulging in the desire or action whatever it may be. We should remain where we are and do nothing, rather than run the hazard of doing wrong. The language of the Apostle is applicable in a case of this kind. "Whatsoever is not of faith [that is, is not done in the faith or belief of its lawfulness] is sin."
