not in the passion of lust, even as the Gentiles who don't know God;
      3. The arguments with which the apostle enforces his exhortation. (1.) They had been informed of their duty. They knew their Master's will, and could not plead ignorance as an excuse. Now as faith, so knowledge, is dead without practice. They had received of those who had converted them to Christianity, or been taught of them, how they ought to walk. Observe, The design of the gospel is to teach men not only what they should believe, but also how they ought to live; not so much to fill men's minds with notions as to regulate their temper and behaviour. The apostle taught them how to walk, not how to talk. To talk well without living well will never bring us to heaven: for the character of those who are in Christ Jesus is this: They walk not after the flesh, but after the Spirit. (2.) Another argument is that the apostle taught and exhorted them in the name, or by the authority, of the Lord Jesus Christ. He was Christ's minister and ambassador, declaring to them what was the will and command of the Lord Jesus. (3.) Another argument is this. Herein they would please God. Holy walking is most pleasing to the holy God, who is glorious in holiness. This ought to be the aim and ambition of every Christian, to please God and to be accepted of him. We should not be men-pleasers, nor flesh-pleasers, but should walk so as to please God. (4.) The rule according to which they ought to walk and act--the commandments they had given them by the Lord Jesus Christ, which were the commandments of the Lord Jesus Christ himself, because given by authority and direction from him and such as were agreeable to his will. The apostles of our Lord Jesus Christ were only commissioned by him to teach men to observe all things whatsoever he had commanded them,Matthew 28:20. Though they had great authority from Christ, yet that was to teach men what Christ had commanded, not to give forth commandments of their own. They did not act as lords over God's heritage (1 Peter 5:3), nor should any do so that pretend to be their successors. The apostle could appeal to the Thessalonians, who knew what commandments he gave them, that they were no other than what he had received from the Lord Jesus.
