Much of modern debate is framed in terms of rights. The right to life, the right to marry, equal rights.
For abortion, this is "reproductive rights".
An article at Science Daily made me think about this, but I am not going to address the article directly.
There is a interesting paradox for Christians.
Only Christians can make a valid claim for "God-given rights". I have yet to hear a good argument from atheists about where rights come from. Most seem to be sliding into a gray area, where rights are whatever those in power decide they are (thus driving the competition for power and influence).
At the same time, the Bible urges us not to fight for our rights - but to put aside our rights in love and service to others (to put the needs of others ahead of the exercise of our rights).
Of course, when a direct command from God is in question (such as murder and abortion), then it is right to protest and disobey (within the limits of the law).
The ultimate escalation available being to put aside our rights entirely - allowing the government to imprison or even kill us. Never to overthrow the God-given authority of government.
