A will is a reference to one’s goal, a resolve or other determination for an ends. With God, the Divine Will is simple because it rests on the nature of God, as do all of God’s attributes. That being said, because God is love, His will is His love and His love is His will.
Let God = Will = Love = Essence
Therefore He freely participates by necessity in loving creatures which He moves, and by His movement, they each participate in the Divine Will. Inside this will, inside its complete necessity, inside the essence of God to love and will His creation, is non-excess, nor a loss, but a perfect, un-thwart-able-ness that unfailingly brings love to all creation. His immutability only adds to this cause, where God’s love for His creatures (us) is unchangeable.
Evil though, is the lack of this goodness. It is not the essential or occasional disappearance of good by nature, but must be willed to diminish in a thing. The pain or hardship or things we understand as “evil” in this world are only in the equation of love and will for goodness by God in the world. By contradiction God cannot impart evil on anything.
This will of God is given to man through both reason by the thoughtful man, and in revelation to a hard hearted people.
To study the Summa Theologiae, I highly suggest doing so with Verbum from Logos bible software. Verbum is a state-of-the-art library that connects thousands of resources so that you can study a subject with layers of depth, analysis, and understanding. If you’re new to the Summa, you really need companion material and it’s all available in the Verbum package. For example, each Question and Article in the Summa sources several other documents of the Magisterium, other philosophers, Church Fathers, etc., – and Verbum connects them all, so that in one click, you can explore and connect the Tradition of the Church easily and scholarly. I use Verbum everyday, no exaggeration, it’s that important to me. Learn more about Verbum here.
