My favorite conversion in Acts is the conversion of Cornelius. Why? With Cornelius being the first devout Gentile to be baptized into Christ, his conversion allowed me to become a child of God also. His conversion also had to be one with convincing evidence to be accepted by the Jews. I believe there were two things that convinced Peter; the blanket in chapter 10 and the descending of the Holy Spirit.
This conversion is one the most mis-understood conversions by the “faith only” denominational world.
