A lot of Christians feel an obligation to be politically pro-life. But is Jesus actually pro-life? Rather than boxing Jesus in a partisan issue, I think everyone agrees that he is pro-love. In the book of John, when an adulteress was brought to him to be executed according to conservative law, Jesus showed her love instead. He didn't judge her lifestyle, didn't slut-shame her, didn't condemn her for her choice. He loved her and gave her a second chance. Pro-life means pro-women's-lives. An unborn fetus is not more valuable than the woman who bears it.
For the most part, people will choose to do whatever they want to do, and the law can't force them to change. You can't legislate morality. You can't force someone to comply with your religious beliefs, and certainly can't use the law to do so (that's what Islamic extremism is). But if you show kindness and love, like Jesus did, that's how you institute change.
Women will elect abortions whether they are legal or not. Illegalizing abortion does not stop abortion. It merely forces women to perform them under unsafe conditions, and then punishes them for their choice afterwards. Illegalization is not pro-life, it is pro-punishment. If we really wanted to be like Jesus, we should be pro-love.
