The percentage of control shifts minute by minute and day by day, depending on a number of factors involving our health, our relationships, our culture, and those individuals who decide it's their mission to lord their own "perfected" ideology over as many other people as possible.
We have 100% control over the choices we make and we are constantly making choices in life. We are esp held accountable for every idle word we speak. People will have to give an account on judgement day. Matthew 12:36.
