sunday insight

I'd like to be:
-humble; to keep my body on the ground.
-obedient; to keep on the good track.
-active; to be and to live the optimum me.
-creative; to keep my mind open, sharp, and fresh.
-brilliant; to improve things do better things for the living things.
-kind; because living in a kind+safe world is everyone's dream, every place is home.
-generous; for better future.
-tough; so that I don't complain.
-happy; so that others would be happy too.
-friendly; so that I don't judge people by their look.

I went to the church for Sunday Mass, it's the 3rd week of Lent. Then some questions came to my mind:
1. We (human) have different stage of understanding, talent, capability, characteristic, etc --so it makes sense if people just vary in being obedient to God. How exactly God or The Church expect the society to be? --since everybody just do not understand as clearly as others' think, perform as well as others' do, and give as much as others' do.
2. (it's about heaven) I read that "we'll fill with joy and happiness, every day will be like festivals!". You'll have everything you want (while you're deeply in love with God, up there.) So why exactly did the Satan fell from there?
3. So in heaven. We will live in constant super-joy/ecstasy-kind-of-thing for eternity?? whaw..will we be conscious? duh.
anyway..I just write --I usually think and solve 'em my way.
