The Apostle Paul was in prison in chains and facing a death sentence. He wanted to write this letter to remind Timothy to be strong when he was gone. He reminded him that we must die with Christ to live with Christ. He reminded him how important and useful the Word of God was and not to abuse the Word. He reminded him that because he was young he faced lustful temptations that he must avoid. Once you are caught in these temptations you will be ensnared by the devil. Therefore flee them.
