Romans 16:19 For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil. 20 The God of peace will soon crush Satan under your feet. The grace of our Lord Jesus Christ be with you.
A hallmark is a mark stamped on articles of gold, silver, or platinum in Britain, certifying their standard of purity or genuiness. The hallmark of a true Christian is obedience to the Lord Jesus Christ. Please note from Paul’s letter that the Roman local church is considered obedient, not perfect. Paul wrote to bring correction to the obedient local church of Rome. Jesus states quite clearly in Matthew 7:21-23 that people who know Him and are known by Him seek to do His will. Do you have the hallmark of a genuine Christian, the desire to obey the teachings of Jesus? Do you attempt to obey the Lord Jesus expecting Him to fulfill your attempt with His power? Do you actively read and study the Bible to know what to obey? If you can answer yes to all the questions then your obedience will be known to all, not your perfection.
As believers live in obedience to Jesus, those in authority over them will have joy (Hebrews 13:17). As believers live in obedience to Jesus they will be wise to what is good and innocent as to what is evil. Obedience to Jesus benefits all people, because doing what is good benefits all people.
God has defeated Satan on the cross (Hebrews 2:14-15) and will cause him to flee as believers submit to Jesus and resist the devil (James 4:7). As Paul stated earlier in the letter, every believer is more than a conqueror in Christ (Romans 8:37).
The grace of the Lord Jesus Christ be with you. Grace is unmerited favor and the total of God’s resources needed to live a godly life. It is grace that makes it possible for every believer to obey Jesus.
