Thus we have a pattern for understanding growth and perseverance in faith and discipleship. This pattern is exemplified by the apostle Paul, who before conversion was “a Pharisee, a son of Pharisees” (Acts 23:6)—“the strictest party of our religion” (Acts 26:5)—and “as to righteousness under the law, blameless”(Phil. 3:6). The cross, however, exposed the ambitions of his heart, and thus here counts the truth of his condition: “We ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days inmalice and envy, hated by others and hating one another” (Titus 3:3). So Paul can declare at the end of his life, “I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his unlimited patience as an example for those who would believe on him and receive eternal life” (1 Tim. 1:16). - John P. Harrigan, the Gospel of Christ Crucified, p.237
