Feeling God's finger in the word's work confirms it is divine
Word cannot so work without men feeling God's finger in themselves.
They own a divine efficacy moving the mind within.
That felt force becomes a new argument: this word is truly divine.
Paul to Thessalonica: received as God's word, which works in you who believed (1 Thess 2:13).
Latin
XLVI. Ista vero Dei verbum in hominum animis operari non potest, quin ipsi digitum Dei in se sentiant, & agnoscant divinam quandam efficaciam, quae intus eorum animos miris & variis modis commovet & afficit. Nec possunt mentem eo referre, quin inde valide in fide confirmentur, & novo quodam argumento colligant vere divinum esse verbum illud cujus tam divinam vim & energiam in se persentiunt. Quo spectat Apostolus dum gratulatur Thessalonicensibus quod verbum auditus Dei accepissent, non ut verbum hominum, sed sicut vere est, ut verbum Dei, quod & (inquit) operatur in vobis qui credidistis, 1 Thess. 2.13.
