The Lord Jesus begins by telling us that we are the salt of the earth. That means that the believers have a preserving and savoring effect on the world as salt does to earthly things. The eminent Bible commentator John Gill writes the following on this phrase:
Ye are the salt of the earth,.... This is to be understood of the disciples and apostles of Christ; who might be compared to “salt”, because of the savoury doctrines they preached; as all such are, which are agreeable to the Scriptures, and are of the evangelic kind, which are full of Christ, serve to exalt him, and to magnify the grace of God; and are suitable to the experiences of the saints, and are according to godliness, and tend to promote it: also because of their savoury lives and conversations; whereby they recommended, and gave sanction to the doctrines they preached, were examples to the saints, and checks upon wicked men.[2]
We are not only the salt of the earth but also the light of the world. The believers have an important task in the world, indeed as some have said, the world stands for the sake of the elect. But what we also learn from v. 15 is that others benefit from the light, meaning other people than us should benefit from our works. Our light, which is our character, deeds and walk in the Lord, should move others to seek God and see God in us. Therefore, it is undoubtedly true that all good works should be done to the glory of God and that thereby the glory of God may be manifested to others.
The apostle Paul also says:
1 Cor. 10:31 So, whether you eat or drink, or whatever you do, do all to the glory of God.
Anything that we do in life should be done to the glory of God, whether it be good works or studying, or eating and drinking. We should do all things with thankfulness to God and to His honor and glory. In a passage mentioned above, we see again that good works brought forth through faith are to be for Christ’s glory (1 Thess. 1:11-12). The God Who works in us to do His pleasure and equips us to be able to carry out His holy will, is also the God Who works all things according to His purpose and therefore to His glory (Phil. 2:13; Heb. 13:20-21; Eph. 1:11; 2:10).
§2 These good works...are the fruits and evidences of a true and lively faith
- These good works, done in obedience to God’s commandments, are the fruits and evidences of a true and lively faith; 1 and by them believers manifest their thankfulness, 2 strengthen their assurance, 3 edify their brethren, 4 adorn the profession of the gospel, 5 stop the mouths of the adversaries, 6 and glorify God, whose workmanship they are, created in Christ Jesus thereunto, 7 that having their fruit unto holiness they may have the end eternal life. 8
