The Gospel In US Jails And Prisons

In the US, jails and prisons allow visiting Christian representatives to hold worship services.
They teach and preach the Gospel of Jesus. They teach about regeneration. They teach about the fruit of the Holy Spirit which is love, joy, peace, patience, kindness, gentleness, goodness, faithfulness and self-control.  Those virtues help people become better human beings.  Jesus never ever encouraged anyone to murder someone else. The first Christian converts were all Jews.  The first Gentile convert in the history of Christianity was a Roman Soldier.  He was a Centurion.  His name was Cornelius.    The Bible is silent about his life after his conversion.
