Contribute financially to organizations that support the condemned and their families. A death sentence is an emotional and spiritual blow not only to the condemned person but also to members of their family. Organizations that reach out with Christian sensitivity to those suffering this kind of an assault are always worthy of support. Unfortunately, the principalities and powers that rule this nation are not likely to abandon their love of death anytime soon. As Christians, we need to educate ourselves about the realities of capital punishment and must support organizations that speak out against it.
Many states have excellent organizations as well.
Beware, however, of organizations that suggest that the death penalty be replaced by life sentences without parole. That option is as unbiblical and un-Christian as capital punishment, for the God who raises the dead is also the God who frees the prisoner. Mourn for all those who are put to death. Murder and capital punishment are an assault on us all, especially those who seek to live in a deep, personal relationship with Jesus. Every time a killing occurs, we all feel the pain, the horror, the sin.
