Eternity is the very essence of God, in so far as that essence involves necessary existence. To conceive things therefore under the form of eternity, is to conceive them in so far as they are conceived through the essence of God as actually existing things, or in so far as through the essence of God they involve existence. Therefore our mind, in so far as it conceives itself and its body under the form of eternity, necessarily has a knowledge of God, and knows that it is in God and is conceived through Him.
We delight in whatever we understand by the third kind of knowledge, and our delight is accompanied with the idea of God as its cause.
From the third kind of knowledge necessarily springs the intellectual love of God. For from this kind of knowledge arises joy attended with the idea of God as its cause, that is to say, the love of God, not in so far as we imagine Him as present, but in so far as we understand that He is eternal; and that is what I call the intellectual love of God.
He who clearly and distinctly understands himself and his emotions rejoices, and his joy is attended with the idea of God, therefore he loves God, and (by the same reasoning) loves Him better the better he understands himself and his emotions.
This intellectual love necessarily follows from the nature of the mind, in so far as it is considered, through the nature of God, as an eternal truth. If there were anything, therefore, contrary to this love, it would be contrary to the truth, and consequently whatever might be able to negate this love would be able to make the true false, which, as is self-evident, is absurd. There exists, therefore, nothing in Nature contrary to this intellectual love, or which can negate it.

This love to God above everything else ought to occupy the mind, for this love is connected with all the modifications of the body, by all of which it is cherished.
The idea of God which is in us is adequate and perfect, and therefore in so far as we contemplate God do we act and consequently no sorrow can exist with the accompanying idea of God; that is to say, no one can hate God.
Love to God cannot be turned into hatred. But some may object, that if we understand God to be the cause of all things, we do for that very reason consider Him to be the cause of sorrow. But I reply, that in so far as we understand the causes of sorrow, it ceases to be a passion, that is to say, it ceases to be sorrow; and therefore in so far as we understand God to be the cause of sorrow do we rejoice.
