Some indeed preach Christ from envy and rivalry, but others from good will. The latter do it out of love, knowing that I am put here for the defense of the gospel. The former proclaim Christ out of selfish ambition, not sincerely but thinking to afflict me in my imprisonment.
Night and Day
Paul tells Timothy that he prayed night and day for him.
Why pray “night and day”? Prayer is a sign of care; thanksgiving is a sign of contentment, even joy. Paul’s desire is that Timothy, who began well under Lois and Eunice, continue to move forward. So Paul demonstrates care by praying, and rejoices in the progress he observes.
