Finally then, brothers, we beg and exhort you in the Lord Jesus, that as you received from us how you ought to walk and to please God, that you abound more and more.
That as ye have received of us how ye ought to walk, and to please God. The walk of believers is twofold, either internal or external. Their internal walk is by faith, which is the going out of the soul by faith to Christ for every supply of grace. Their external walk is not as it was before conversion, according to the course of this world, or as other Gentiles walk, but in a holy religious life and conversation; and this requires spiritual life, strength and direction from Christ; for neither dead men, nor, if alive, yet weak, can walk; nor is it in a spiritual man, that walketh to direct his steps; and such a walk also denotes continuance, in well doing, and a progression or going on in it, and supposes ways to walk in. Christ, he is the chief and principal way, and there are other paths which regard him, or relate and lead unto him; as the way of truth, the path of ordinances, and of religious worship, both public and private, and the ways of righteousness, holiness, and good works: the manner in which saints are to walk is as Christ himself walked, after the Spirit, and not after the flesh, according to the rule of the word, which is the standard of faith and practice, with prudence, wisdom, circumspection, and worthy of God, and of that calling wherein they are called: and of such a walk there is a necessity; it "ought", it must be both on the account of God, it being his will, and for his glory, and the contrary would show great ingratitude to him; and on the account of the saints themselves, to adorn them, and their profession, and preserve them from shame and disgrace, to show their faith, and demonstrate their calling and election to others; and likewise on account of others, partly for the winning of some, by recommending in this way the Gospel to them, and partly for the bringing of others to shame and silence, who falsely accuse their good conversation. Now when the apostle, and those that were with him, were at Thessalonica, they gave these saints directions and instructions about their walk and conversation, to order it in such a manner as might "please God"; which is not to be understood of rendering their persons acceptable to God hereby, for the saints' acceptance with God is only in Christ the beloved; nor of their gaining the love and favour of God by such means, for the love of God is from everlasting, and is free, and sovereign, and does not arise from, or depend upon the holiness and obedience of men; or of making peace with God by such a walk, for peace is only made by the blood of Christ; but of doing those things, and in such a way God approves of: unregenerate men cannot please God, nor anything they do, because they are destitute of the Spirit of God, and are without Christ, and his grace and have not faith in him, without which it is impossible to please God; but what a believer does in faith, from a principle of love, in the name and strength of Christ, and to the glory of God, is approved of by God, and is acceptable to him through Christ, and for his sake; and there are many things of this kind, as prayer, praise, acts of beneficence to the poor, and indeed every good work and holy action: and inasmuch as they had been thus taught and instructed how to behave and conduct in their outward walk and conversation, they are entreated and exhorted to go on and abound in the work of the Lord:
