NOT ASHAMED OF THE GOSPEL
To the philosophers of Rome (the elite), a little Jewish tentmaker coming to preach about a poor Jewish carpenter who was crucified was almost humorous.
But the apostle Paul wasn't ashamed to preach the powerful gospel message that changes lives. It had transformed his own life.
Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to everyone that believeth; to the Jew first, and also to the Greek.
The Gospel of Salvation delivers sinners from the penalty and power of sin. Salvation is the greatest need of the human race.
