Those who see the Beatific Vision (saints in heaven, angels who chose to serve God), see the Good with a capital G. In this life, our free will presents to us various small goods with lowercase g’s (“apparent goods”) and, informed by our intellect, we “move” our will toward whichever we think will make us happiest. All the while, we are, in a sense, in the dark about what will make us absolutely and truly happy. We can’t fully apprehend the final end of our choices – the Good with a capital G – because we can’t see it. However, once it has been presented to us in its definitive form, in the beatific vision, our will both *cannot *and would not want to choose otherwise. The function of the will is to choose the Good. The Good is directly in front of the will. So there is nowhere else to go. We experience complete satiety, complete happiness, no lack of anything that would be required for our complete joy. This is the case for everyone who has chosen, based on trust in God (faith) and confidence in his promises (hope) to love him by obeying his commandments and loving his children (charity). For the angels, as has been said above, the beatific vision was not immediately presented to them. They were given some knowledge (we don’t know exactly what) and therefore a choice to serve God. Some, Lucifer the first among them, said, "Non serviam." They made their choice based on pride (an unwillingness to trust in God).
