Long before the conscious mind wakes to it, something deeper already holds the shape of what a person is meant to become. The old language calls this foreknowledge: not a fate forced from outside, but a pattern of wholeness carried inside from the very start.
The spirit's work is that pattern slowly coming true. To obey the inner Christ is to let this deeper center guide the everyday self instead of fighting it, and the blood means the change reaches past mere ideas into the body and the instincts, into how a person actually lives. When someone finally moves in step with what was always waiting inside them, the inner war ends, and that wholeness is what brings the peace.
