Thank you Spiritus for that link, I took the test and according to results I am Melencholic.
Ah, a fellow Melancholic! Nice.
When God creates our soul does He infuse our personality within it?
That's somewhat of a difficult question for me to answer. While I would be inclined to say yes, personalities can also change over time. For instance, when I was younger I'd say I was more of a Sanguine than a Melancholic, because I was very energetic and outgoing, whereas a Melancholic is more quiet and prefers to be alone as opposed to socialising. Within the last several years, however, although I'm more outgoing than the average Melancholic, I have become a bit more quiet and laid back.
Most of the traits of a Melacholic - sensitive, artistic, easily embarassed, low self-confidence at certain times, etc. - fit me to a tee. I'd also say I'm still partly Sanguine, which explains why I'm more outgoing and talkative than the average Melancholic, but I've become more Melancholic over the years.
Also: If God knows all things, does He know when He creates our soul if we will win Heaven?
I was pondering just this morning, that very point. If God knows at the moment our soul is created and before it is infused within the fetus that we will not cooperate with His grace, is He then creating something evil?
Can God create an evil?
No, God creates good, He only allows evil.
Then my mind started to think of the fallen angels and did God know which angels would fall before He created them? If yes, then is God creating an evil?
God knew what angels would would fall, but He created all of them good.
I hope this helps.
