The Gospel is the power of God and is simple enough for a child to grasp.. or for a college professor to get it. Tell it clearly. I love how far reaching It can be. It's for whosoever hears and wants this salvation. God freely offers salvation by grace alone through faith alone in the work of Jesus Christ alone to the Glory of God alone. It is not at all limited to a specific ethnic group or to individuals of a certain intellectual level or location. God's immeasurable saving grace extends to all, without distinction of race, income level, nationality, ethnicity, or intellectual ability. Why? It's cuz He loves us all the same.
Paul said, "For I am not ashamed of the Gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek." 1/16rom
