God & Satan Edit
Some think that he is like God, but the opposite (evil). This is not true at all, Satan fighting God would be like a mosquito not being crushed by a plant falling on it, and even farther beyond that. God is infinitaly more powerful than Satan, so we should have absolutely nothing to fear if we are on God's side rather than Satan.
Satan doesn't make you sin Edit
Satan can't make you sin. He can go no farther than tempt you, it is totally up to you whether you sin or not.
