It is possible for us to choose freely not to act as God acts. When we do not act like God, we are, in effect, trying to become something we are not. We are trying to shape ourselves into something other than images of God. In addition, acting contrary to the very beings we are fills our consciousness with a confusing array of experiential data. Thus, when we analyze this data to gain a knowledge of ourselves, we see an inadequate and marred image of God. The attempt to determine and, subsequently, to know ourselves as something other than images of God never completely succeeds. When we sin—i.e., when we act contrary to the very beings we are, we tarnish or wound ourselves. We try to do the impossible—i.e., we try to destroy our likeness to God. Sin is a suicidal act.
For good or for ill, we become what we do. We can choose to become more God-like or less God-like. Since God creates all men and women in His image and likeness, He invites each one of us to holiness, but He does not force it on us. He not only invites, He offers us the means: grace. But like the call or invitation, the means, God’s grace, is never forced on us.
