God does not want us to live in an environment where mass shootings happen -- and happen far too often. I do not believe this is the way God intends for us to live. God's vision for earth is a reign of justice and peace. God's desire for humanity is to love and live in harmony.
If we are honest, we all have an agenda. My own agenda is shaped by a passage my mom taught me, Micah 6:8. It teaches that what God requires is that we seek justice, love mercy, and "walk humbly with our God."
