1 Finally then, brethren, we urge and exhort in the Lord Jesus that you should abound more and more, just as you received from us how you ought to walk and to please God; 2 for you know what commandments we gave you through the Lord Jesus. (1 Thessalonians 4:1–2, NKJV)
While some say obeying the commands of God is not essential for eternal salvation in Christ, the apostle encourages Christians to abound more and more in that very lifestyle. The word “ought” conveys a moral obligation. That is, we are morally required before God to walk (live) so as to please Him (2 Corinthians 5:9). Living to please God is accomplished by keeping the commandments we have been given by the apostles “through the Lord Jesus” (1 Corinthians 14:37). Stay the course of faithfully obeying the commands of the Lord Jesus, and Christ will give you eternal life (Hebrews 5:8-9). We can never be content with not pleasing God, as if our sin carries no eternal consequence. They do. Therefore, let us “abound more and more” in a life of faith that keeps the commands of God.
