Vs. 6, “For God, who said, “Let light shine out of darkness,” made his light shine in our hearts to give us the light of the knowledge of God’s glory displayed in the face of Christ.” When Paul was persecuting the church and on his road to Damascus, the light shined in the darkness of his life and his heart (Acts 9). Paul knew there were those who were still blinded (vs. 4) by their own hard hearts and the deception of the enemy. There were false teachers with ulterior motives, but this was not what Paul was doing. But none of these challenges would stop Paul. For he knew the treasures and promises that God has for us (vs. 7-18). Though we may look like simple jars of clay (vs. 7), there is incredible value in them! Though there is much suffering and opposition (vs. 8-10), Paul reminds us our life does not belong to us (vs. 11-15). In the troubles of life, we just need to step back sometimes and gain perspective that these troubles are so short compared to the joys of this life and eternity (vs. 16-19).
Regarding application…Don’t Lose Heart! Vs. 16, “Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day.” Paul is repeating this encouragement again from vs. 1. Question: Have you ever been discouraged with church and serving God? Welcome to the spiritual battle (Ephesians 6). But despite Paul’s hard ministry, Paul would not give up. Despite all the physical toil and opposition, Paul would not give up. Question: How was this possible? Because Paul understood God’s incredible mercy (vs. 1) and spiritual formation of Paul’s heart (vs. 16). Notice how we are reminded that we are inwardly renewed day by day! Not just once or twice a week, but daily! Just as we feed our bodies day by day, God desire to renew us inwardly day by day through Bible reading, prayer, living out our lives, serving the church, etc. Paul reminds us in the book of Romans 8:31, “If God is for us, who can be against us.” Don’t lose heart brothers and sisters!
