Today is not the day for problem-solvers to get into debates about causes and solutions. I understand that people grieve in certain ways, but, debates are the absolute last thing that grieving families, whose hearts are screaming out against evil and injustice, who are crying in pain, want to hear, and need to hear. They don't want solutions; they want and need love and compassion. They don't need to hear about gun-control, or stronger security measures; they need emotional, physical, spiritual, and psychological support. While problem-solving has an appropriate time and place, its time is not now.
So, for the love of God and love of neighbor, mourn with those who mourn.
Love. Pray. Listen. Pass the peace.
The LORD is near to the brokenhearted, and saves the crushed in spirit.
