IMO, the spiritual significance of abortion is about choice, responsibility, and consequence.

This means that any wrong or right answer is strictly relative to your situation and condition. Are you being frivolous? Or, are you really in dire circumstances? People generally know for themselves what choice to make. And then there's always the question, who owns a woman's body? Is it the woman? Is it her fetus? Is it her boyfriend? Is it God? who actually makes that choice?

Everything we do, everything we react to tells us who we are. The better we listen, the more we know. Life happens in order to assist this.
