The city of Boston is like a family in a way, and this family has just been through the ringer. They welcomed a couple of guys into their fold who in turn decided to stab their fellow Bostonians in the back. Dzhokhar and Tamerlan betrayed the very community that had opened their arms to receive them. It seems unbelievable that this could happen, and yet it did.
Likewise, Jesus welcomed Judas into the ranks of His disciples. To repay Him for this kindness, Judas decided to hand Jesus over to death in exchange for 30 pieces of silver. Betrayal beyond belief, like the bomber brothers who brought death, injuries and pain to many innocent people. Judas couldn't care less for the close-knit group of disciples he had entered, or the Savior who had loved him. Judas was only out for himself.
The bomber brothers chose to be consumed with evil. When a person makes that choice, there is no telling how far he will be willing to go to fulfill the raging desires of his heart. Evil leads man to hate God and to hate others. It unleashes its fury in unpredictable ways. And innocent people tend to be the victims of this dangerous fury.
