ISB ~ Galatians 1 v13

I persecuted the Church:A dark chapter in Paul’s pre-Christian life, of which he was later ashamed (1 Cor 15:9; 1 Tim 1:13). His zeal for traditional Judaism spurred him to adopt violent and aggressive tactics that included harassing, imprisoning, and even executing early Christians (Acts 8:1-3; 9:1-2; 26:9-11). After his conversion, Paul’s fiery enthusiasm was not lessened but given new direction by Christ.
