Shame is a tool our enemy uses against us, and we use against each other (and on ourselves, because many of us shame ourselves). When we feel trapped in shame, worthless, and wanting to hide, shame wins.
Our enemy wants us to feel shame in such proportions that we feel there is no use, we feel hopeless, discouraged, debilitated, and a victim. Because then we feel like an outcast from others and God. We feel unlovable. The more we feel these things, the probability is we will self-medicate with unhealthy behaviors, solutions, and addictions, and then feel even worse.
Shame wants to win at all costs and never has good intentions towards us.
