Timothy should be a good leader in the
Some Christian leaders had prayed for Timothy at some time before Paul wrote this letter. See 1 Timothy 4:14. They had spoken words from God to Timothy. Perhaps God had said that he would make Timothy strong. Timothy needed to be strong so that he could be a Christian leader.
Timothy did not have to fight anyone and hurt them. Paul did not mean that. He meant that Timothy had to be strong and brave to teach the true Christian message. That was how he should ‘fight’ against wrong things.
Paul had told Hymenaeus and Alexander to leave the church. He wanted them to become ashamed of themselves. He hoped that they would learn to obey God.
