Paul used every situation to advance the borders of Christ’s kingdom; he even used prison as an opportunity to further the cause of Christ. While prison robs a person of freedom, family and choices, Paul was not robbed of certain things, such as:
1. HIS PEN. The prison epistles (Ephesians, Philippians, Colossians and Philemon) were all written while Paul was in a Roman jail.
2. HIS PURPOSE. Paul had been chosen to spread the name of Jesus to the Gentiles, kings and the children of Israel (Acts 9:15). His purpose was to preach, and his life was for Christ (Philippians 1:21).
3. HIS PULPIT. Paul was successful in preaching to the elite Praetorian Guard (Philippians 1:14), something possibly unattainable had he been a free man. He capitalized upon every situation for the sake of Jesus.
4. HIS PRAYER. While in prison, Paul prayed for the brethren. Ephesians 1:15- 23; 3:14-21; Philippians 1:9-11 and Colossians 1:9-12 illustrate his prayer life on behalf of the saints (cf. Romans 10:1; 2 Thessalonians 7:17; 1 Timothy 2:1-8).
5. HIS PRAISE. Paul and Silas sang praises to God at midnight while in the Philippian jail (Acts 16). Although they were confined, their hearts were full of joy and thanksgiving in the form of melodious song.
6. HIS PATIENCE. Paul was confident in God’s plan for his life; therefore, he endured patiently. He was willing even to postpone going to heaven in order to help the Philippian Christians in their spiritual growth (Philippians 1:21-25).
7. HIS PEACE. Paul found peace in Jesus Christ. He said, “I have learned in whatever state I am, to be content” (Philippians 4:11). Furthermore, he wanted the Philippians to know that while prison was a place of capture, the Gospel was continually preached (Philippians 1:12).
Paul is a great encouragement to all Christians. Though in trials, he was triumphant; though in chains, he was challenged. Paul was confined, but not controlled; restrained, but not restricted; incarcerated, but not incapacitated. Paul was in prison, but prison did not rob him of the most important thing in life – his desire to spread the Gospel. Therefore, Paul can be described as the apostle of the heart set free.
