So sad to hear that your son also experienced it. But as time goes, so we get over it. I told the robbers that I will pray for them and a couple of weeks later the cops came to tell me that they have both been killed during another robbery.
So good that they caught the guy that robbed your son, at least there is a degree of closure in that.
Blessings!
If I remember correctly, they caught him, but he was killed while resisting police arrest. Well perhaps God's answer was that no more innocent people should be attacked. I also I think that praying for someone who has done us harm brings peace to ourselves.
