In the book “The Science of Evil” written by Simon Baron Cohen, empathy and compassion are lost when we lose and show contempt for the sanctity of human life. This applies to both Christians and non-Christians. From that exchange begins hatred, cruelty, and suffering.
It is far too common that our pre-meditated thoughts are bent on the termination of another human life when it comes into a violation of our personal beliefs and/or standards. We think of a violent response when a person intrudes on our domicile, place of work or worship. Is this the proper perspective as it compares to Scripture relative to that response? If an act is perpetrated at our workplace, is a premeditation to murder equal to vigilantism? How far does the vigilantism go? Will we take our judgment to the point of a proactive response and terminate a life based on perceived intent? These are questions we must answer.
Typically, the Beatitudes have been something that Scripturally apply to an individual’s action and interaction with another, even one who is our enemy. Civically , institutions of law enforcement are in place to address criminal activity at large. Nationally, a military and militia are in place to ensure a righteous response by a government to preserve and protect its citizens. “Does the government bear the sword for nothing?” (Romans 13:4)
We are to encourage the kind of conduct one should expect from a government installed by God. 1 Peter 2:13ff. says, 13 Submit yourselves for the Lord’s sake to every human authority: whether to the emperor, as the supreme authority, 14 or to governors, who are sent by him to punish those who do wrong and to commend those who do right. 15 For it is God’s will that by doing good you should silence the ignorant talk of foolish people. 16 Live as free people, but do not use your freedom as a cover-up for evil; live as God’s slaves. 17 Show proper respect to everyone, love the family of believers, fear God, honor the emperor.” (NIV)
The accountability to God of our actions will weigh on a proper discernment of our expectations as a Christian.
