Yes, there are Muslims who commit horrible acts of violence. But violence is not unique to Islam. It is common to all humanity. In our fallen depravity, all of us are radicalized by sin.
This is not a Muslim problem.
This is a human problem.
We need to get our stories straight, because the Gospel of Christ does not discount anyone from grace and salvation… even terrorists. Take Paul, who started out as a religious militant, overseeing the execution of Christians he saw as infidels because he thought that put him on God’s winning side.
He went on to become the author of most of the New Testament.
