The third act of faith.

Herman Witsius has written:

“That which follows this assent is the love of the truth thus known and acknowledged; and this is the third act of faith, of which the apostle speaks, 2 Thes. ii. 10. For since there is a clear manifestation of the glory of God, in saving truths, not only as he is true in his testimony, but also as his wisdom, holiness, justice, power, and other perfections shine forth therein, it is not possible but the believing soul, viewing these amiable perfections of the deity in those truths, should break out into a flame of love to exult in them and glorify God. Hence the believer is said to give glory to God, Rom. iv. 20. and to love his praise (glory), John xii. 43. Above all, the soul is delighted with the fundamental truth concerning Christ. Loves it as an inestimable treasure, and as a pearl of great price; it is precious to believers, 1 Pet. ii. 7. yea, most precious. It is indeed true, that love strictly speaking, is distinguished from faith; yet the acts of both virtues, or graces, are so interwoven with one another, that we can neither explain nor exercise faith without some acts of love interfering; such as is also that of which we now treat…”
