Two delights in conflict: the stronger carries the will
Thesis LXI. A person's mind is often touched at once by some sense of delight toward opposite things. Especially in believers, as long as they carry this mortal body, there is a struggle between two delights, one earthly and the other heavenly, one harmful and the other helpful; and whichever wins draws the mind after it, inclined and consenting.
It can never turn out otherwise than that the greater delight carries the will off toward what delights it more. Wherever the mind stands between righteousness and sin and is pulled two ways, it must act according to whatever has delighted it more.
Latin
LXI. Cum vero saepe contingat hominis animum circa opposita aliquo delectationis sensu simul affici; ac praesertim in fidelibus, quamdiu corpus hoc mortale gerunt, lucta fit duarum delectationum, unius terrenae, alterius coelestis, unius noxiae, alterius beneficae: utralibet vicerit, animum secum pronum & consentientem trahit. Nec unquam aliter evenire potest, quam ut major delectatio voluntatem rapiat in illud quod magis delectat. Ac ubicunque animus, inter justitiam & peccatum constitutus, in diversa trahitur, quod amplius delectaverit, secundum illud operetur necesse est.
