Only God has the authority to take human life. But God has ordained that he should exercise that right through the power of the state. Romans 13:4
says the governing authorities are God’s servants to do good, “but if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God’s wrath on the wrongdoer.” The Navy SEALs that raided bin Laden’s compound did not violate the sixth commandment because, as the Heidelberg Catechism says, “Prevention of murder is also why government is armed with the sword” (Q/A 105). Surely, this was an instance where the U.S. military, by killing bin Laden, was acting in an effort to prevent more American citizens from being murdered.
