Having stated several facts about the salvation that God has provided, the apostle Paul proceeds to give a series of four commands telling believers how to live. Living to please the Lord, having been freed from the tyranny of sin, does not mean the believer's pursuit of holiness will be without ongoing effort. The commands given in this section are instructions for the believer's behavior and how sin must be dealt with. The believer thinks differently about sin since sin no longer rules over the heart, mind, and will. Thoughts dwell on how to please God while refusing to respond to any and all appeals by sin, or attractions to sin. Thinking right about sin then must be followed up by the deliberate decision not to give sin any opportunity to control attitude or actions.
The grace of God, past, present, and future is the believer's blessed hope. The grace of God has appeared in the person and work of Jesus Christ. That grace in the past provided salvation of sinners who will come to God by faith alone, in Christ alone. The grace of God for the present, "now age" teaches and enables saved sinners to live consistent with their new character. Being so taught the believer lives a life of worship and obedience anticipating the future grace of God to reappear in the person of Jesus Christ. When He does, He will complete the transformation of believer's lives into perfect conformity with His character. The world may be falling apart but our great God and Savior is coming again. With that great hope we, who have been saved by the grace of His first appearing, endure, persevere, and rejoice, as we await His glorious return.
