God. Grace means there is nothing we can do to make God love us more --no amount of spiritual calisthenics and renunciations, no amount of knowledge gained from seminaries and divinity schools, no amount of crusading on behalf of righteous causes. And grace means there is nothing we can do to make God love us less --no amount of racism or pride or pornography or adultery or even murder. Grace means that God already loves us as much as an infinite God can possibly love.
