Question:

What's the role of God? spectator? or can He actually influence/change others?

Refer to the section on the Trinity for the answers to this one.  He is very active and in total control through the persona of the Holy Spirit.

• God is all-powerful and is so involved with what happens that not even a sparrow falls to the ground apart from His will (Mt. 10:29).

• He is in control of history. Paul declared that "He has made from one blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings" (Acts 17:26).

• He also declared that the rulers of nations, bad as well as good, receive their authority from God (Dan. 4:17; Rom. 13:1).

• He decides to whom He will show mercy instead of wrath (Ex. 33:19; 34:5-7; Rom. 9:14-24).

• He has chosen those who will be the redeemed in heaven (Jn. 6:37; Rom. 8:28-29; Eph. 1:4).

• He was involved when Pharaoh refused to listen to Moses and determined not to release the Israelites from slavery in his land (Ex. 5-14).

• He was even involved in the treachery of Judas Iscariot in that He provided the circumstances that made it possible for Judas to fulfill his preordained role (Acts 1:15-20).

• God is active in history, even when He doesn't seem to be. This theme runs through the entire Bible.

One very favorite verse concerning the control and the will of God -- More than 30 years after being the victim of his brothers' hatred, Joseph quieted their fear of retaliation by saying:

Do not be afraid, for am I in the place of God? But as for you, you meant evil against me; but God meant it for good, in order to bring it about as it is this day, to save many people alive.
