Cap. II Sol. Arg. 3: love shows who receive glory — not foresight-cause of the decree
Reply: "for those who love him" tells what sort of people finally receive the glory he prepared from eternity — it does not make foresight of that love the cause why glory was destined to them. The same love that freely destined them to glory also destined them to love God, and by that love they take the road that leads to glory. So our love of God is an effect of the divine love that elected and predestined us to salvation — foolishly taken as election's cause. So the Apostle: "We love God because he first loved us" (1 John 4:19).
Latin
Verba illa, iis qui diligunt eum, ostendunt nobis quales tandem illi omnes sint, quibus ab aeterno gloriam praeparavit: sed non indicant hanc dilectionem praevisam fuisse causam aut rationem cur gloria fuit illis destinata. Idem amor Dei qui eos destinavit gratuito ad gloriam, destinavit etiam eos ad hanc dilectionem Dei, qua impellente viam ineunt quae recte ducit ad gloriam. Est itaque nostra Dei dilectio effectum amoris Divini quo nos elegit & praedestinavit ad salutem, atque idcirco inepte supponitur causa nostrae electionis. Huc spectant illa Apostoli verba, Nos diligimus Deum quia ipse prior dilexit nos. 1 Joan. iv. 19.
