This word proves that, in his life and work, Paul took the Lord's appearing and His kingdom as the incentive and goal. The Lord's appearing will be for judgment, to reward each one of us (Matt. 16:27; Rev. 22:12), and His kingdom will be for His reigning with His overcomers (Rev. 20:4, 6). The apostle not only took these two matters as the incentive and goal for himself but also by these two matters charged Timothy, who was under his leading, to faithfully fulfill his ministry of the word.
