The central character of Hans Christian Andersen's fairy tale The Little Mermaid dreams of giving up her life in the sea to find love on dry land. The agony she undergoes exchanging her tail for a fully human form is poignant. It makes one wonder what it would be like to become another sort of thing, something we've desperately wanted to become.
Even before the Fall, human beings longed for dramatic change. In Genesis we see that Eve longed to be like God, to share in his very wisdom and goodness (Gen. 3:5-6). That longing was not the problem, since we see that in Christ, we are destined to "participate in the divine nature" (2 Pet. 1:4). Rather, the problem was that Eve grasped at God's wisdom and goodness instead of waiting and trusting God to fulfill her God-given longing.
