The Spirit assists
Meanwhile, the assistance of his Spirit is supposed during the whole process of the inquiry. Indeed it is not easy to say in how many ways that assistance is conveyed. He may bring many circumstances to our remembrance, may place others in a stronger and clearer light; may imperceptibly open our mind to receive conviction, and fix that conviction upon our heart. And to a concurrence of many circumstances of this kind in favor of what is acceptable in his sight, he may superadd such an unutterable peace of mind and so uncommon a measure of his love as will leave us no possibility of doubting that this, even this, is his will concerning us.

25. *Meantime, the assistance of his Spirit is supposed, during the whole process of the inquiry. Indeed ’tis not easy to say, in how many ways, that assistance is conveyed. He may bring many circumstances to our remembrance, may place others in a stronger and clearer light; may insensibly open our mind to receive conviction, and fix that conviction upon our heart. And to a concurrence of many circumstances of this kind, in favour of what is acceptable in his sight, he may superadd such an unutterable peace of mind, and so uncommon a measure of his love, as will leave us no possibility of doubting, That this even this, is his will concerning us.
