The Senate is 3,500 years behind Moses. Thou shalt not commit murder. The commandment is not against all killing, just murder. God ordered the Israelites to exterminate the sinful Canaanites. God ordered the execution of murderers.
Human governments have trouble with number two and number three.
Instead of acknowledging God's authority over who may be killed, human governments what to set themselves up as the authority. Instead of acknowledging that unborn babies are people, endowed by their Creator with inalienable rights, human governmnents want to decide who is a person, and who isn't. We are at a crucial decade in our nation's history. Or will we slip further down the slope away from God, and give God's authority to the government, which will then become God and decide who is a human being and who isn't, and who has a right to live and who doesn't. There are powerful forces at work on both sides.
