Most Southerners never heard of Dominionism and Trump has consistently won the Evangelical vote all over the South. Looks like more of the same in Miss.
The Gospel of Salvation is achieved by setting up the "Kingdom of God" as a literal and physical kingdom to be "advanced" on Earth in the present age.
Some dominionists liken the New Testament Kingdom to the Old Testament Israel in ways that justify taking up the sword, or other methods of punitive judgment, to war against enemies of their kingdom.
Dominionists teach that men can be coerced or compelled to enter the kingdom.
They assign to the Church duties and rights that belong Scripturally only to Jesus Christ. This includes the esoteric belief that believers can "incarnate" Christ and function as His body on Earth (where have we heard that?) to establish His kingdom rule.
An inordinate emphasis is placed on man's efforts; the doctrine of the sovereignty of God is diminished.
