In Question 7, I supposse I didn't interpret in Genesis, that God made all the angels when he made the heavens.Yup, that's what happened. Here are the verses in question:
Gen 1:1 In the beginning God created the heavens and the earth.
Gen 2:1 Thus the heavens and the earth were finished, and all the host of them.
By "the host of them" is meant "all who inhabit them." This would include the angels. See also these verses:
2 Praise him, all his angels, praise him, all his host!
5 Let them praise the name of the LORD! For he commanded and they were created.
Col 1:16 for in him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or principalities or authorities--all things were created through him and for him.
Now, on to your next question:
So, my question is how did God choose the personalities of the angels?By His divine Providence.
Are the angels listed somewhere and how many are there?Well, we know that their are 9 offices, or orders, of angels, and these are all listed in the Bible:
- Angels: see here
- Archangels: 1 Thes 4:16; Jude 1:9
- Virtues: Eph 1:21
- Powers: Eph 1:21; Col 1:16
- Principalities: Eph 1:21; Col 1:16
- Dominations: Eph 1:21; Col 1:16
- Throne: Col 1:16
- Cherubim: see here
- Seraphim: Isa 6:2,6
Daniel 7:10 A stream of fire issued and came forth from before him; a thousand thousands served him, and ten thousand times ten thousand stood before him; the court sat in judgment, and the books were opened.
Matthew 26:53 Do you think that I cannot appeal to my Father, and he will at once send me more than twelve legions of angels?
Revelation 5:11 Then I looked, and I heard around the throne and the living creatures and the elders the voice of many angels, numbering myriads of myriads and thousands of thousands
Now on to your next question:
How did God choose the personalities of the saints?Again, by His divine Providence.
In God's plan, do you think that everything is planned out-miracles and events-or does He make things happen as we go along?Everything is most certainly planned out!! If he just made things happen as we go along, then that would mean that he was a temporal being. But, he is outside of time. All things appear to him in an instant. He does not grow in knowledge or experience. He does not change. He is immutable and omniscient.
Also, do you think that humans will ever achieve world peace through Christ?We can make peace more prevalent in our world, but ultimate, perfect world peace will not be established until Jesus Christ, the Prince of Peace, comes again in glory.
In which case, I often wonder, is it possible for life to exist without evil?Yes. Life exists in heaven without evil. Life in the Garden of Eden before the fall was life without evil (unless you count the presence of the serpent as an "evil"). When Jesus comes again and eradicates all evil, life will continue. So, it is possible. But, we live in the span between the beginning and the end where there is evil, and it will always exist until the Second Coming. This is not entirely unfortunate, thanks to the wonderful grace of God.
