Why do you belive in god?

I would definitely agree with you here. That one of the most powerful thing for is that the universe was created by him. All the beautiful creation on the earth, the animals even our amazing body and how it works amazes me. No one takes for granted the fact that a gorgeous house was designed,and built by someone. The universe, the earth, the animals humans themselves all are far more amazing and complex compared to a home and that tells me that God created all these things. Also I would say fullfilled Bible prophecy gives me confidence in God. The things that are fullfilled prophecy in the Bible and have been shown alongside with historical evidence gives me more confidence in God as well.

Because the universe is good, it's humans who make these sad things like killing animals, hurting kids, leaving their elderly parents, killing each other. But the universe it self is harmonious and good.

it is a good question...mmh.probably because it would be grotesque thinking that life is just a casual things and there are not ancronology about events happening to us...

I believe what you refer to is the connective source energy that flows through everything. I believe we are the gods, and that we have the power to be joyous and loving creators. There is no ominous spirit that makes everything happen. Its everything that makes everything happen. Its all connected to a base source energy that lives naturally to be loving, appreciative, and feeling good. That makes me so powerful that we can direct our lives with love to create anything we can imagine and actively seek.
