2 radical opposites

In Paul the Apostle, we have 2 radical opposites.

On one hand, he was the blasphemous persecutor, making havock of the church.

On the other hand, we've got the greatest missionary the church has ever known.

How does one go from the absolute radical worst, to the absolute radical best?

Only one thing can make this type of radical difference: the GOSPEL of Jesus Christ.

The GOSPEL is STILL the answer!

Romans 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
