As I write, one alleged Boston Marathon bomber is dead; the other is on the run. Both, apparently, are Muslim; both have been in the US for more than a decade. The younger brother was an excellent, scholarship-winning student and captain of his high school’s wrestling team. The older brother was a boxer.

These young men grew up in schools and in communities like those around Charlotte. They played sports, they hung out with friends, they worked hard in school.

And then they attempted to commit mass murder.

How should we respond to this shocking tragedy?

Here are four biblical guidelines:

First: We all rightly long for justice. Our God is the moral authority in the universe. He will see to it that all sin are paid for, all wrongs duly punished. Vengeance is not in our hands as individuals (Romans 12:19). Our anger and bitterness and vitriol will not effect justice (James 1:20). In the present age, however, God has provided the government to act as His “servant, an agent of wrath to bring punishment on the wrongdoer.” (Romans 13:4)

Second: Your prayers matter. In light of government’s heavy responsibility, the Apostle Paul instructs us:

I urge that supplications, prayers, intercessions, and thanksgivings be made for all people, for kings and all who are in high positions, that we may lead a peaceful and quiet life, godly and dignified in every way. (1 Timothy 2:1-2)

So may we thank God for the hundreds of police who, right now, are tracking down the fugitive – many risking their lives. May we lift up civil servants and political leaders who make decisions about lockdowns and public transport and school closures. May we pray for judges and attorneys should the fugitive be captured and tried. And may this episode end with increased confidence throughout our nation that our authorities will act bravely and professionally to enable us to live peaceful and quiet lives.

Third: Life is fleeting. Lu Lingzi, Martin Richard, and Krystle Campbell woke up this Monday excited to watch friends and loved ones run the Marathon. They had plans for that evening, this weekend, and years into the future. And in a flash, murderers snuffed out their lives.

How long do I have in this world? How long do you? We have no idea. As James tells us:

Come now, you who say, “Today or tomorrow we will go into such and such a town and spend a year there and trade and make a profit” – yet you do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little time and then vanishes.  Instead you ought to say, “If the Lord wills, we will live and do this or that.” As it is, you boast in your arrogance. All such boasting is evil (James 4:13-16).

James is not telling us to forget about plans for the future. Rather, we must live knowing that we are dependent, fragile creatures, living and breathing today by the mercy of God. Thus, we should live humbly before the eyes of our all-knowing, all-seeing, all-sovereign Lord, confessing that He knows best, and gladly subjecting ourselves to Him, for His glory.

Finally: Your light matters. The deceased alleged bomber wrote, “I don’t have a single American friend, I don’t understand them.” Note that he came to the US more than ten years ago. Yet Scripture instructs us:

When a foreigner lives with you in your land, you must not oppress him.  You must regard the foreigner who lives with you as the native-born among you. You are to love him as yourself, for you were foreigners in the land of Egypt; I am the LORD your God.  (Leviticus 19:33-34)

What might have happened if a follower of Christ had done unto Tamerlan Tsarnaev as he would that others do to him? How might lives have been changed if followers of Christ had been salt and light in this young man’s life?

And what might happen if you and I love the foreigners among us? If you and I reach out to those who have come to study, to those who have come because of war and chaos, to those who have come because of political oppression?

Our response to this tragedy must not be to shrink back into a fear of foreigners. Our Lord calls us to go, to be light and salt – so that others may see our good works and give glory to our Father in heaven (Matthew 5:16).

Through the sacrifice of our Lord Jesus, we are heirs of eternal life, entrusted with the message of God’s abundant mercy, to be proclaimed to all. May the horror of Boston compel us all the more to be His ambassadors, His heralds, holding out the word of life with love and compassion to all the peoples God has brought to Charlotte.
